The Variable Compression (VC) turbo engine is one of the latest developments in car engines. VC engines provide higher efficiency and consume less fuel by using variable compression ratios inside the piston. <\/p>\n\n\n\n

Here we will provide you with complete details about the working, specifications and benefits of the VC-turbo engine. <\/p>\n\n\n\n

VC-Turbo Engines<\/h2>\n\n\n\n

A VC-Turbo engine is a combination of petrol and diesel engines<\/a>. The efficiency and torque produced by the engine is equal to a 2.0 L petrol engine and the powertrain is of a diesel engine. The turbo engine works by using different compression ratios as per the acceleration. It uses a 14:1 air compression ratio for higher efficiency and an 8:1 ratio for higher performance.    <\/p>\n\n\n\n

Background<\/h3>\n\n\n\n

The first kind of VC-Turbo was introduced in the 2000s but failed to survive in the market. The major cause of this failure was the high cost involved in the manufacturing of these engines. After 20 years of long research, the engine was again introduced recently with a more advanced and efficient manufacturing process.<\/p>\n\n\n\n

Specifications<\/h3>\n\n\n\n

The VC-Turbo is designed to compete with the V6 engines in terms of performance and efficiency. Many VC-Turbo engine specs are similar to inline 4 cylinder engines. However, piston position is different from V and inline engines<\/a>. The bore diameter is 84mm. Whereas, piston strike is not constant and ranges from 90.1 mm to 88.9 mm. The air-cooled charge colour is used for turbocharging which generates 390 Nm of torque.<\/p>\n\n\n\n

The engine also contains two different types of ignition systems to cope with the high and low compression ratio. For low compression ratio spark ignition systems and for high compression, Homogeneous Charge Compression Ignition (HCCI) is used.<\/p>\n\n\n\n

Working<\/h3>\n\n\n\n

To acquire the higher compression ratios<\/a> piston have to compress much harder in the combustion engine. Moreover, turbochargers are also required to capture additional air for the air-to-fuel ratio. This difference in demand ratio is dependent upon the acceleration of the vehicle.<\/p>\n\n\n\n

The VC-Turbo engine contains a harmonic drive reduction gear and actuator that controls the piston movement. When the accelerator is pressed it rotates the reduction gear in clockwise direction which slows down the piston stroke movement. Thus, the compression ratio is lowered and fuel economy is increased. Whereas, at a lower speed, the control shaft comes to its original position bringing the compression ratio to normal and increasing fuel economy.  <\/p>\n\n\n\n

Benefits<\/h3>\n\n\n\n

The 2.0L VC-Turbo engine is a great innovation in combustion engines. Further usage of this technology in combustion engines can make it capable to compete with V8 and V12 engines<\/a>. <\/p>\n\n\n\n
