Chevrolet Trax Turbo Engine

Chevrolet Trax which was imported from the GM factory in South Korea, is capable of producing a power equivalent to 140 horsepower at 4,900 rpm. And with dimensions of 4,245 mm long, 1,775 mm wide and 1,670 mm high, this car is classified as a six-seater compact SUV.

In addition to being equipped with a powerful engine, this car also provides a fairly complete safety feature with six air bags (airbags) as a collision barrier.

Before the car was officially sold in Indonesia, we dissected the 1.4 liter turbo engine produced by GM.

Completing production of its car with a 1.4 liter engine is nothing new for GM. In 2011, the famous United States introduced a 1.4-liter turbo 4-cylinder engine which is one of a series of four engines designed by GM.

The smallest family of 4-cylinder GM engines includes, the capacities of 1.0 liter, 1.2 liter, and last 1.4 liter. Meanwhile, middle class families include 1.6 liters and 1.8 liters. For large engine classes, the manufacturer provides 2.0 liter and 2.4 liter engines.

Especially for the 1.4 liter engine, GM initially provided 2 types for the North American region. Several types of GM cars with this capacity can run up to 100 hp. But with the addition of turbo technology, the 1.4 liter engine can output 140-180 hp.

In an automotive event at the Frankfurt Motor Show last month, GM has also introduced a 1.4 liter engine equipped with ECOTEC Direct Injection Turbo embedded. This engine is a development of the 4-cylinder turbocharger feature by adopting an injection combustion system which consists of two types of output, namely output, 92 kW / 125 hp and 110 kW / 150 hp.

Although heavier than the previous version, the turbo engine with this newer technology can minimize friction on the pistons for a pleasant (quiet) sound. Not only that, this machine is claimed to be cooler than some of the turbo engine variants that GM has made.

TURBO MACHINE IDENTIFY 

Hearing the word turbo, what comes to mind is something fast, fast. It's not wrong, because in a turbo engine there is more air flowing into the cylinder block so that combustion is more spontaneous and bigger. As a result, the resulting thrust is more optimal.

The engine with turbo features is very special, some of the super performance supporting components of this type of engine, made with precise measurements so that it can support the wild energy of Turbo. Here are some of the special components found in the 1.4 liter GM turbo engine:

CYLINDER BLOCK

The engine cylinder block is made of gray cast iron with five reinforcing bearings. This engine block offers exceptional thermal properties that match cylinder pressure and the load generated by the turbocharger system.

In order to reduce the weight of the load, there are also cavities in the frame, making it lighter than conventional beams. Engine with 1.4 L Turbo capacity, uses a unique lubricating system and is able to maximize fuel efficiency.

This variable oil pump system operates according to engine lubrication demands, thus avoiding excessive lubrication capacity that the engine does not really need.

CYLINDER HEAD

The cylinder heads on this engine are made of aluminum with a DOHC (dual over head camshaft) system and four valves per cylinder are used on the 1.4 L Turbo.

With the aerodynamic design of air that enters the cylinder head, it can provide optimization and efficiency to the engine, and make combustion more complete. Not carelessly, for this performance the cylinder is equipped with a special exhaust gas flow that supports the turbo engine exhaust system.

1.4 liter Turbo engine, using a turbocharger that is uniquely integrated with the exhaust manifold. The turbocharger size is selected with an emphasis on low speed torque and gas opening.

This requires slightly more components than a conventional system engine, that is, a system that must control temperature so that it is always maintained in a faster engine heat cycle. The turbocharger itself is lubricated by engine oil and uses liquid coolant to maintain its long term performance.

ELECTRONIC THERMOSTAT CONTROL

This is intended to maintain temperature stability during engine performance to have an effect on fuel efficiency. This control consists of several sensors that monitor engine performance, the optimal temperature point, and the load supported by the engine.

CAR PERFORMANCE WITH TURBO ENGINE

With a machine construction like this, we believe the Chevrolet Trax can compete with the speed of other cars in its class. However, a turbo requires good airflow to work optimally. In traffic jams, these types of machines are usually more susceptible to overheating.

Therefore, the performance of the Trax on the road will depend on cooling components and sensors that have to perform optimally in extreme road conditions. Let's just wait if the 1.4-liter Trax turbo engine can work effectively and efficiently.
