The gapless helical gear transmission designed by German MITEC company is adopted to accurately control the phase between camshaft and valve lift, and ensure the best intake and exhaust phase and ignition time, thus improving power and torque output and reducing fuel consumption. In addition, the transmission efficiency is improved, the transmission noise is effectively reduced, and the durability of camshaft and other parts is improved.
3) Optimized exhaust system
The exhaust system is optimized to make the catalyst more economical, durable and reliable, and avoid the trouble of maintenance as much as possible.
4) Fully balanced crankshaft
The crankshaft of the engine is designed in a completely balanced way. The eight balance weights of the crankshaft can effectively balance the influence of unbalanced centrifugal force of each cylinder during the rotation of the crankshaft, thus improving the reliability of the engine. Fully balanced crankshaft can ensure good NVH quality, effectively reduce the load, noise and vibration of crankshaft and improve the service life of crankshaft.
5) Unique wavy water jacket
The adoption of patented wavy water jacket makes the engine get the most suitable cooling, which not only ensures the cooling performance of the engine even under the worst working conditions, but also makes the engine more durable and reliable, eliminates the excessive cooling of the current general engine and reduces the fuel consumption.
6) High performance independent oil pump
Using high-performance oil pump can lubricate the engine more thoroughly, reduce friction resistance, reduce parts wear, clean and cool the surfaces of parts, and bring solid and reliable guarantee for excellent work and higher power output of the engine. The lubrication system adopts the oil supply in the middle of the main oil circuit and distributes it to both ends to ensure the oil supply and oil pressure of each part, and the operation is reliable. Independent oil pump design, convenient maintenance.
7) High performance combustion system
The patented high-performance air duct and combustion system make the charging efficiency close to 100%, and the gasoline atomization and mixture organization are scientific and efficient, which improves the combustion speed and efficiency, thus improving the torque and power output and reducing the fuel consumption and emissions.
8) Small angle syringe
By using small angle injector and optimizing injection angle, the fuel supply rate is effectively controlled, and the combustion system is matched, so that the mixture structure reaches the best level, the fuel combustion efficiency is improved, and the combustion performance of the engine is significantly improved, which not only improves the power output, but also reduces the fuel consumption and emission standards.
9) High temperature resistant light engine piston
The piston of the engine adopts advanced high temperature resistant aluminum alloy, which is lightweight. Piston movement is easier, engine operation is easier, unnecessary power consumption is reduced, fuel consumption is greatly reduced, and NVH quality is improved.
10) Low tension thin piston ring
Using thin piston ring with low tension, high-quality materials and advanced processing technology can improve the sealing performance of piston movement, reduce friction resistance, minimize friction loss and ensure greater output power.
1 1) ignition system without distributor
The distributor-free electronic ignition system is adopted to improve the working efficiency of the engine, make the fuel burn more fully and reduce the instantaneous fuel consumption.
12) excellent NVH performance.
In the development process, NVH mute technology is developed simultaneously. Through acoustic development and optimization, engine noise is reduced and sound quality is improved.
13) design of high torque cylinder
The cylinder block design adopts a rectangle with a stroke larger than the cylinder diameter, which has the characteristics of low speed and large torque output, so that the vehicle can obtain great power at low engine speed, the acceleration time is greatly shortened, the driving performance of the vehicle is improved and the fuel consumption is reduced.
Fourth, the core advantages:
Changan C 10 engine, as a new benchmark for domestic small displacement engines, has three core advantages-power increase by 30%, life extension by 20% and fuel consumption reduction by 10%.
1) Strength increased by 30%
The output power of C 10 engine reaches 5 1KW, which is 13KW higher than that of the same displacement engine, and the lifting efficiency reaches 30%. It is a self-owned brand engine with the largest power in domestic 1L displacement.
2) the service life is prolonged by 20%
Strict testing ensures the high quality and reliability of C 10 engine. By conservative estimation, the reliability can be improved by more than 20%.
3) The fuel consumption is reduced by 10%
The fuel consumption (40km/h) of the C 10 engine is only 3.2L, which is 10% lower than that of the traditional engine, creating a record of low fuel consumption for domestic small displacement engines. C 10 engine has the characteristics of low speed and large torque output. When the engine speed is 1500 rpm, the emission is 74Nm, and its torque reaches 85% of the maximum torque in the wide speed range of 2000-5000 rpm, which makes the engine and the whole vehicle have faster dynamic response, excellent driving performance and more fuel saving.
