Cruze latest diesel engines


Recently, Chevrolet officially announced a new paragraph will be applied to the 2014 Cruze 2.0L turbo diesel engine technology - variable valve swirl system . According to the official statement, this new technology to create a "perfect storm" in improving engine efficiency , while making the engine emissions more environmentally friendly. What is a "perfect storm" ?Audi A3 turbocharger How it affects engine performance?

Cruze variable valve swirl system

2014 Cruze 2.0L turbo diesel engine corresponding to each cylinder has two intake ports, and one in which the intake air intake manifold connected to an internal opening of the adjustable valve. Depending on speed , load and operating conditions , vehicle automatic control valve opening angle to control the intensity of the gas mixture inside the combustion chamber swirling motion .

At low speed and load conditions , the vehicle is involved in all aspects of the resistance value is larger , then the need to increase the vortex movement inside the combustion chamber of the gas mixture to the engine will not die because of inadequate supplies of fuel the fire , thus improving engine efficiency , the opening of the valve will be very small at this time , causing the valve to the intake valve short vacuum , gas mixture swirl exercise intensity increases.

In contrast, in high speed and high load conditions ,Skoda 1.8 turbocharger the resistance value of the vehicle itself is reduced, this time in order to ensure fuel economy and emissions of environmental protection, a swirling motion inside the combustion chamber of the gas mixture to be reduced accordingly , by increasing the valve opening, so that the intake valve to a small vacuum disappears, then the gas mixture weakening of the vortex motion .
By controlling the valve opening movement manufactured in different conditions of different gas mixtures vortex intensity , thus affecting the efficiency and emissions of the engine , the new engine features are official summed up as " the perfect storm ."

Official data show that the measured , equipped with a "perfect storm" of 2014 Cruze engine can achieve higher compression ratio, hundred kilometers only 5.2 L, fill the tank can be life after more than 1100 kilometers , more than the U.S. in the sale of single- brand gasoline powered vehicles performance should be good . Emissions , and cash Cruze 2014 Cruze compared to emissions of nitrogen oxides to be reduced by 90 %.
