Heilongjiang Garden MachineryManufacturer distributes 170 gear pumps

1. The engine valve drive mechanism adopts a hydraulic support ball rocker arm structure. Compared with the hydraulic tappet valve drive mechanism commonly used in gasoline engines, this novel valve drive mechanism has the advantage of relatively small friction torque, and therefore requires less driving force, which can effectively reduce engine power consumption and fuel consumption.

2. To effectively reduce the overall weight of the vehicle, the 1.4-liter gasoline engine adopts an aluminum alloy cylinder body, achieving a very significant lightweighting effect.

3. The use of specialized materials and plastic intake pipes processed by special techniques instead of traditional metal intake pipes not only achieves lightweight effects, but also effectively reduces intake pipe wall resistance, improves intake efficiency, and increases engine power.

4. Heilongjiang gear pump adopts advanced technology to process the expansion type connecting rod, and uses dedicated expansion equipment to expand and break the processed connecting rod big end hole, instead of the original sawing and grinding process. This can utilize the serrated "Haff" surface of the connecting rod to ensure accurate fastening and positioning, thereby reducing friction and extending the service life of the connecting rod.

5. Adopting a hot sleeve camshaft not only reduces the weight of the camshaft compared to the original camshaft, but also achieves higher cam profile accuracy and more accurate valve timing.

6. The throttle adopts an electronic control device, also known as E-GAS electronic throttle. This control device can unify and manage the instantaneous requirements of engine torque and output power for various working conditions of the car, such as driver acceleration, overtaking, starting air conditioning, etc., so that the engine's operating state at each working point is always within the appropriate range, which can 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 and increase the intake density, allowing the engine to output greater power while improving the charging efficiency. The specific improvement is to arrange the intake pipe of the engine on the left side of the front module of the engine, above the cooling water tank.

8. To improve the anti-corrosion ability of the cooling water tank and extend its service life, the cooling fins of the cooling water tank arranged in the front module of the engine are all wrapped in plastic.

9. To prevent collision and friction between the bottom of the engine oil pan and uneven road surfaces, which may damage the engine, a metal protective plate can be specially installed under the oil pan.

10. To effectively isolate heat, sound, and vibration, and prevent it from entering the passenger compartment and affecting riding comfort, the POLO sedan has installed a heat shield plate at the exhaust pipe.
