1. The upgrade point of Ling Du's third-generation EA888 engine-the third-generation EA888 engine carried by Ling Du has been further optimized on the basis of the original second generation, and the layout and material selection of the whole engine compartment have also been readjusted. The first is the upgrade of the engine, and the most important thing is the "weight reduction" of the engine itself. The overall weight loss was 32kg, equivalent to 1 8-year-old child. Don't underestimate this weight loss. Its practical significance can not only improve weight and power, but also reduce fuel consumption due to slimming. Moreover, it can make the counterweight of the front and rear car bodies more reasonable and let users experience a better sense of control.
In addition, the details of the engine cylinder block vary greatly, such as adding four screw holes to connect with the oil pan to improve stability, adjusting the direction of water channels in the cylinder block to improve heat dissipation effect, optimizing the timing chain and clamping structure to make the transmission effect higher and the wear resistance stronger; Not only that, EA888 also uses two-stage centrifugal oil-gas separator and simplified oil filter to reduce fuel consumption and so on.
These details are simple to say, but the technical difficulty is very great. For example, the structure of the clamping device mentioned above only accounts for a small part of thousands of parts of the engine, but its durability will directly affect the meshing degree between the timing chain and the gear. Therefore, the brand-new EA888 engine can really let users enjoy the effect of "maintenance-free+higher reliability" after optimizing the chain and tensioner structure.
Finally, I want to mention the technical core of EA888. For example, the variable valve lift technology (AVS) has attracted much attention to improve the power output strength at low speed, while the turbocharger cylinder is made of stainless steel, and the pressure value of the injector is increased from the original 150Bar to 200Bar. In addition, the layout of intake and exhaust manifolds has also been optimized to improve the efficiency of power output.
