Hyundai kappa engine 1.4

The 1.25-liter and 1.4-liter Hyundai G4LA and G4LC units of the Kappa family were released by the manufacturer as the main engines for medium and compact car models. These motors were very liked in Europe, in Russia they are found only in Rio, Solaris and Picanto.

Detailed description of G4LA, G4LC engines

The G4LA engine is smaller, its exact displacement is 1248 cm3. Valve adjustment is not required, as the system is equipped with automatic hydraulic lifters.

Timing drive – metal chain. Phase regulator type Dual CVVt. On the 2017 Kia Picanto, the engine consumes about 5.8 liters of fuel in the city, 3.7 liters on the highway.

The G4LC has a feature – the presence of the VIS system, designed to increase torque by changing the geometry of the intake manifold. This innovation has long been used by Toyota, which has developed advanced technology and successfully uses it on multi-valve internal combustion engines.

Otherwise, the engine is similar to the G4LA, but larger and more powerful. On the 2017 Hyundai Solaris, the engine consumes 7.2 liters in the city, 4.8 liters on the highway.

The 1.4L G4LC engine began to be produced in 2015 and installed on Hyundai (Hyundai) and Kia (Kia) cars, instead of the 1.4 G4FA engine, which
produced until 2018. The new G4LC now belongs to the Kappa series engines (Kappa), and the old one to the Gamma series (Gamma).

G4LC has 2 phase shifters unlike the old G4FA. He also lost weight by 13.9 kilograms, changed the connecting rods and the crankshaft with thinner necks. The engine power was reduced from 107 horsepower to 99.7 hp.

You can increase the power by 10 hp. , programmatically upload a new firmware. This is used by dealers and when buying a new car they always offer to do this.

The 1.4L G4LC is currently only available in Korea. Now they began to install hydraulic compensators on the motors, which were not on the old internal combustion engines and had to adjust the thermal clearances of the valves every 100,000 km. The G4LC added a VIS system that is capable of
change the geometry of the intake manifold and increase the torque.

The Hyundai Kappa family of gasoline engines has been produced in India and Korea since 2008 and is installed on almost all compact or mid-size models of the Korean concern. Such power units are conditionally divided into two generations, as well as motors of the Smartstream line.

First generation Hyundai Kappa engines

In 2008, Kappa family gasoline units debuted on the Hyundai i10 and i20 models. These were quite typical engines for that time with distributed fuel injection, a 4-cylinder block made of aluminum with cast-iron sleeves and an open cooling jacket, an aluminum 16-valve cylinder head equipped with hydraulic compensators and a timing chain drive. The first generation of such engines was not equipped with a variable valve timing system.

The first line included only one single power unit with a volume of 1.25 liters:

1.25 MPi (1248 cm³ 71 × 78.8 mm)

In India, due to the peculiarities of tax legislation, such an engine had a volume of 1197 cm³.

Second generation Hyundai Kappa engines

In 2010 in India and in 2011 in Europe, second-generation Kappa series engines appeared, which were distinguished by the presence of a Dual CVVT phase control system on both camshafts. The new family has been seriously expanded due to the appearance of 3-cylinder power units, as well as engines with direct fuel injection, turbocharging or hybrid modifications.

The second line included 7 engines with distributed, direct injection and turbocharging:

1.0 MPi (998 cm³ 71 × 84 mm)

1.0 T-MPi (998 cm³ 71 × 84 mm)

1.0 T-GDi (998cc 71 × 84mm)

1.4 MPi (1368 cm³ 72 × 84 mm)

1.4 T-GDi (1353 cm³ 71.6 × 84 mm)

1.6 Hybrid (1579 cm³ 72 × 97 mm)

Hyundai Kappa Smartstream engines

In 2018, the Hyundai-Kia concern introduced a new family of Smart Stream power units, within which many Kappa series engines, conditionally of the third generation, appeared. Such motors have just appeared and detailed information about their features has not yet been collected.

It was also on these internal combustion engines that a number of new technologies for the Korean concern debuted: for example, an atmospheric combustion engine in one of the versions received a DPi dual fuel injection system, and the supercharged unit is equipped with the latest CVVD variable valve timing system.

The third line so far includes only seven powertrains, but it is still in the expansion stage:

1.2 MPi (1197 cm³ 71 × 75.6 mm)

1.5 DPi (1498 cm³ 72 × 92 mm)

1.5 T-GDi (1482 cm³ 71.6 × 92 mm)

Hyundai G4LC engine

The 1.4-liter 16-valve Hyundai G4LC engine was introduced by the company in 2014 and is primarily known for such popular models on our market as Rio 4 and Solaris 2. In Europe, this power unit was found on i20, i30, Ceed , Stonic and Accent fifth generation.

In 2014, the 1.4-liter internal combustion engine of the Kappa family debuted on the second generation of the i20 model. This is a typical engine for its time, equipped with multiport fuel injection with an aluminum block, cast iron sleeves, a 16-valve head with hydraulic lifters, a timing chain drive and Dual CVVT phasers on the intake and exhaust camshafts. There is also a plastic intake manifold with a VIS geometry change system.

Shortcomings, breakdowns and problems of the G4LC engine

The only widely known problem with this power unit is the oil burner. The manufacturer has lightened the design of the motor by 14 kg compared to the G4FA engine, and by 150,000 km lubricant consumption often appears due to wear of the connecting rod and piston group.

A simple leaf chain is installed here, but due to the low power of the motor, it has a decent resource. However, for active drivers, the chain stretches quickly.

On the forums, they complain about the vibration load of this unit, the noisy operation of the nozzles, the modest resource of the water pump and periodic leaks of oil and coolant.

The manufacturer declared the engine life of 180,000 km, but usually it runs up to 300,000 km.

A brief overview of the design of such a power unit

The company introduced the 1.4-liter turbo engine Hyundai G4LD or 1.4 T-GDI in 2016. In our market, such a power unit is installed on the third generation Ceed and the XCeed crossover. Since 2019, this motor has been included in the new Smartstream line, where it is known under the G1.4T index.

Description of the G4LD engine 1. 4 turbo

In 2016, a 1.4-liter turbo unit appeared on the Elantra model for the American market. The first version developed 130 hp, but when the engine reached Europe it was raised to 140 hp. This is a typical power unit of the Kappa family with an aluminum block, cast iron sleeves, an aluminum 16-valve cylinder head with a direct fuel injection system and hydraulic lifters, a timing chain drive, and a Dual CVVT phase control system on two camshafts. The turbine of own production Hyundai Wia with the article 28231-03200 is responsible for supercharging.

The manufacturer initially equipped the engine with oil nozzles for piston cooling and revised the design of the exhaust manifold, so scuffing is almost never found here.

Disadvantages, breakdowns and problems of the G4LD engine

Since there are piston cooling nozzles and the problem with scuffing is not acute, the main reason for the appearance of a progressive oil burner is the ellipse of the cylinders. The aluminum block with thin cast-iron sleeves and an open cooling jacket has low rigidity, and the presence of a turbocharger only accelerates the deformation processes.

In the turbine units of the Korean concern, a reliable bush-roller chain is used, but it tends to stretch to 100,000 km if the engine is often turned to cutoff. It is good that the replacement of the chain is carried out by each service and is quite inexpensive.

Like any direct injection engine, this one suffers from carbon deposits on the intake valves. It is also not uncommon for oil and coolant leaks to occur due to weak gaskets.

The manufacturer declared the engine life of 180,000 km, but usually it lasts up to 250,000 km.

Malfunctions of Hyundai G4LA and G4LC engines

Here are the most common problems with these motors.

Problems, shortcomings and malfunctions of the 1.4L G4LC engine

Many car owners with the G4LC kappa engine complain about the engine noise. Unpleasant knocks appear on a run of 100,000 km, but there have been cases at 50,000. It is still not completely clear what this is connected with. They write that it can start after removal
catalyst

Some change hydraulic lifters. To replace them, you need to buy 16 pieces. In practice, hydraulic lifters are changed without removing the camshafts, but if you go to an authorized dealer, they will tell you to remove the valve cover, camshafts and, in addition, to replace them
change the crankshaft seal. The problem was solved for a while, but then knocks began again, on a warm car it was clearly audible.

Some workshops say it’s the chain guide and rockers. But as it turned out later, replacing them also did not save the situation.

Many motorists changed oil to another manufacturer and even chose a different oil viscosity. But the knock on the hot again manifested itself.

Many masters say that this is the play of the camshaft, which began to develop on the bed on which it rests. In fact, when removing the bed and subsequent troubleshooting, it is difficult to detect wear. Even if you hold your finger, nothing is felt either.

As a result, as practice has shown, neither the replacement of the hydraulic compensators in the G4LC, nor the replacement of the chain and its damper, nor the frequent oil change and the change of the oil manufacturer solve the problem, and everyone agrees that this is a design feature and an oversight of engineers.
So if you are a perfectionist, then it is pointless to spend money on replacing parts that will not save the situation.

2) Butter Eater G4LC

Many owners of a car with such an engine note an oil burner. Even when buying a new car and changing the oil in it every 7,000 km on a run of 100,000 km, it still consumes 70 grams per 5,000 km. At the same time, the internal combustion engine compression remains normal within
11.6;11.4;11.6;11.5. Such cases do happen, but they are not widespread.

G4LC Engine Maintenance

Due to the poor quality of the fuel, it is worth changing the oil every 7,500 km. For internal combustion engines, 0W-30 or 5W-30 is provided. An oil change requires 3.3 liters, but the total volume for lubrication is 3.7 liters.

The engine has a timing chain drive and, according to the manufacturer’s regulations, the chain does not change over the entire service life. In practice, the replacement of the timing chain is required every 200,000 km, to a greater extent depends on the style and nature of the ride. If the chain breaks or jumps, it can bend
valve.

Unlike the previous generation motor, it is not required to adjust the thermal clearances of the valves here, since hydraulic compensators have been added.

Spark plugs are recommended to be changed every 60 thousand km, then misfires appear.

Attachment auxiliary belt travels 120,000 km.

The fuel filter needs to be changed every 60,000 km.

Due to which fuel economy and weight reduction of Kappa Engine engines are realized

In general, Kappa Engines were made for the sake of fuel economy. The new development coincided with a statement by the president of Hyundai, who said he was interested in reducing fuel consumption and reducing harmful emissions. “The Kappa 4-cylinder engine is representative of the required product,” said Hyundai’s technology manager.

The first car to receive a new engine under the hood was Ai10. This is a mini-car on which an ultra-compact G4LA was installed. Checking fuel costs showed the best result – 5 liters per 100 kilometers! For this class, this is unique.

But that’s not all. The motor pollutes the atmosphere less than the power plants of opponents. So, in the course of comparative tests it turned out that CO2 emissions amounted to only 119 g / km. Fiat Panda, Punto, Opel Corsa, Renault Twingo and Nissan Micro have much higher figures.

In its class, the Kappa series also has enviable torque characteristics – 9.6 kgf / m per liter of volume. These parameters are the best suited for moving around the city, when you need to periodically accelerate and stop.

The advanced technologies used in assembling the motors of the new series made it possible to reduce the weight of the unit and friction costs. Never before seen fuel economy is just the result of this. The cylinder block is made of aluminum, casting was carried out under pressure. This significantly reduced the weight of the motors. For example, the 1.2-liter engine of this series began to weigh 82.4 kg.

It turns out that Kappa is the lightest unit among analogues in the class. Hyundai designers also managed to reduce the mass of engines by combining the engine mounts with the timing cover. Separately, work was carried out to reduce the weight of the pistons – a new skirt was developed, which is smaller than the standard one. At the same time, the overall piston size has also been shortened.

It is noteworthy that the crankshaft main bearings for engines of this family have a frame structure, protected by covers. This greatly increases the degree of rigidity. Cylinders use strong liners, as pistons can easily damage the soft walls of the BC. Sleeves differ in high characteristics of wear resistance.

However, the most significant development was the offset of the crankshaft axis. For the first time, a Korean manufacturer implemented such technology on Gamma series engines. You can imagine a design innovation like this: usually the center line of the cylinders is ideally located with the axis of the crankshaft, but in Kappa units it is somewhat shifted to the side.

What does it give? The influence of lateral forces, which inevitably arise during the course of the pistons, is reduced. The result is reduced fuel consumption, the engine starts to work more stable, noise and vibrations are not so noticeable.

Other Features of the Kappa Motor

The Kappa family is the 11th in the line of Hyundai gasoline engines.
