Engine Technology Features

1. The engine valve drive mechanism uses a hydraulically supported spherical rocker arm structure. Compared with the hydraulic tappet valve drive mechanism commonly used in current gasoline engines, this new type of valve drive mechanism has the advantage of relatively small frictional torque, so the required driving force is also smaller, which can effectively reduce engine power consumption and fuel consumption.
2. In order to effectively reduce the overall vehicle weight, the 1.4-liter gasoline engine uses an aluminum alloy cylinder block, and the lightweight effect is very obvious.
3. Using special materials and specially processed plastic intake manifolds instead of traditional metal intake manifolds not only achieves a lightweight effect but also effectively reduces the intake manifold wall resistance, improves intake efficiency, and increases engine power.
4. Using expansion connecting rods processed with advanced technology, the expansion equipment is used to expand and fracture the connecting rod big end hole after processing, replacing the original sawing and grinding process. In this way, the serrated "Khufu" surface of the connecting rod can be used to ensure absolutely accurate and tight positioning, thereby reducing friction and extending the service life of the connecting rod.
5. By using a hot-fitted camshaft, compared with the original camshaft, not only the weight of the camshaft is reduced, but also higher cam profile accuracy and more precise valve timing are achieved.
6. The throttle uses an electronic control device, also known as an E-GAS electronic throttle. This control device can coordinate and reasonably manage the instantaneous requirements of engine torque and output power under various operating conditions of the vehicle, such as driver acceleration, overtaking, and starting the air conditioner, ensuring that the engine operates in the optimal range at each operating point to meet the requirements of low emissions and low fuel consumption, and optimize the overall driving performance of the vehicle.
7. Improving the layout of the engine intake system can effectively reduce the intake temperature of the engine, increase the intake density, and allow the engine to output greater power based on improved charging efficiency. The specific improvement method is to place the engine intake pipe on the left side of the front module of the engine and above the cooling water tank.
8. In order to improve the anti-corrosion ability of the cooling water tank and extend its service life, all the fins of the cooling water tank located in the front module of the engine are covered with plastic.
9. To prevent the bottom of the engine oil pan from colliding and rubbing against uneven roads, thereby damaging the engine, a metal protective plate can be installed under the oil pan.
10. In order to effectively isolate noise and vibration and prevent them from entering the passenger compartment and affecting riding comfort, the POLO car has installed a sound insulation cover at the exhaust pipe.
