Technical features of the engine
Category:
1. The engine's valve actuation mechanism features a hydraulic-support ball rocker arm design. Compared to the more commonly used hydraulic tappet system found in conventional gasoline engines, this innovative valve drive boasts significantly lower frictional torque, resulting in reduced actuation force. Consequently, it effectively minimizes engine power consumption and helps lower fuel usage.
2. To effectively reduce the overall vehicle weight, the 1.4-liter gasoline engine features an aluminum-alloy cylinder block, achieving a remarkably lightweight design.
3. By using specialized materials and plastic intake manifolds processed with a unique technique instead of traditional metal ones, we not only achieve weight reduction but also effectively minimize intake pipe wall resistance, enhancing air intake efficiency and ultimately boosting engine power.
4. The connecting rods are manufactured using an advanced process that involves expanding the big-end bore with specialized expansion equipment, rather than the traditional method of sawing and grinding. This innovative approach leverages the toothed "havf" surface created during the expansion process, ensuring perfectly precise clamping and positioning—resulting in reduced friction and significantly extending the service life of the connecting rods.
5. By using a press-fit camshaft, not only is the weight of the camshaft reduced compared to the original design, but it also achieves higher cam profile accuracy and more precise valve timing.
6. The accelerator is equipped with an electronic control system, also known as E-GAS (Electronic Throttle). This advanced control mechanism seamlessly coordinates and efficiently manages the engine's instantaneous torque and power output requirements under various driving conditions—such as when the driver accelerates, overtakes, or activates the air conditioning. As a result, the engine operates optimally in every scenario, ensuring both low emissions and fuel efficiency while simultaneously enhancing the vehicle's overall driving performance.
7. Improving the layout of the engine's intake system can effectively reduce the intake air temperature and increase air density, enabling the engine to deliver greater power while enhancing its charging efficiency. Specifically, the intake manifold has been repositioned to the left side of the front engine module, above the coolant tank.
8. To enhance the corrosion resistance of the cooling water tank and extend its service life, all the cooling fins in the engine front-end module are coated with plastic.
9. To prevent the engine oil pan from colliding with or rubbing against uneven road surfaces and potentially damaging the engine, a metal protective plate can be optionally installed beneath the oil pan.
10. To effectively insulate against heat, sound, and vibration—preventing them from entering the passenger compartment and disrupting ride comfort—the POLO sedan features an additional heat shield installed in the exhaust pipe area.
