need to ensure a sufficient flow area, and a cross section to avoid turning mutations to improve the surface finish of the pipe, to reduce drag. In high performance gasoline engine intake system using linear, and rational design of airway throttle and the intake pipe length, an appropriate arrangement of the regulator chamber volume to achieve high rpm, high power. In addition to the requirements of the engine power, but we must also have good economy and emissions performance. On the gasoline engine, the intake pipe must also consider the combustion atomization, evaporation, dispensing, and using a pressure wave and so on. In diesel engines, also called via the intake air flow is formed in the cylinder intake swirl, to improve mixture formation and combustion. This requires us to harmonize the process according to the application.
an exhaust pipe
The main material of the exhaust pipe is stainless steel, and take over the ferrule may be made of stainless steel or aluminized steel. In order to achieve vibration and noise reduction, and easy to install system life to prolong the effect of the exhaust muffler, exhaust pipe will generally mounted between the engine exhaust manifold and the muffler, and the exhaust system as a whole flexible coupling.
an exhaust pipe mainly for light trucks, mini trucks and buses, motorcycles, exhaust pipe structure isDouble-clad steel wire bellows sleeve, both ends of the structure of the straight section of the outer collar, so that the muffler is better results, the corrugated tube can be equipped with an internal telescopic section, or nets.
2. Maintenance
1. Engine valve clearance and carburetor, air filter, etc. should be promptly adjusted correctly according to the vehicle and cleaning instructions, such as the valve clearance is too small or mixture is too thick, too thin will affect the combustion, the impact on the muffler cause discoloration.
2. In order not to affect the cooling of the engine and the muffler, and a muffler of the engine is not installed in front of the windshield or other decorative items;
3. No large load for a long time with a low gear; [ 123]
4. when mounting the muffler, the muffler should be noted that the pad in place, and a good fastening, to prevent leakage, so as not to affect the muffling effect at the interface and cause the muffler yellow;
5. not H-throttle-situ high speed for a long time;
6. when the muffler to clean up surface stains;
7. A hard winter cold start, choke off the engine start, hot car Note that the time to open the choke;
8. Do not close the choke for a long time under high speed state.
car maintenance to pay attention to the usual details, go to a lot of attention to some inconspicuous place, sometimes to look at, a little more attention, I think they can reduce a lot of trouble.
