摘要:"Chain machine" and "plunger machine" what is the difference?
1, plunger machine and the chain is in the different structures of valve-train, size and the torque is not necessarily. 2, structurally, chain machine is more advanced. Chain machine under the same displacement can by improving the speed and increase power. Small size light weight, small mechanical load, ignition accurately, to combine a lot of advanced technology are used together. So the high performance cars loin basic chain machine, but at the same time, the manufacturing technical requirements are higher. Plunger is not suitable for high speed machine itself, foster strengths and circumvent weaknesses, so most of the cylinder bore little large travel, so distance increased, and avoid the high speed, low speed (common areas) torque is big, accelerate the powerful, climbing performance is strong, good practicability. Chain machine can also be done in this way, the easiest way to change the cylinder diameter and schedule with respect to OK, but high speed performance than the chain machine plunger machine. Chain machine generally focus on the high speed power output (do not change the cylinder capacity under the condition of increasing diameter, shorten the trip to improve speed, physical sense: per unit time is working more, and, of course, the output power is great!), to increase speed to increase strength, the chain machine under the high speed of explosive force is powerful, so the car will turn around 8000 ~ 10000 began to play. Namely, the characteristics of different emphasis is different. As for the vibration problem is caused by many factors, for small displacement car, chain and push rod is not the deciding factor. 3, when it comes to durability problems, is relative. Abroad such as some of the more than 1500 cc V duplex ultra large cruise vehicle, torque is staggering, more than 2000 turn speed is more than 140 yards, commonly used speed not more than 4000, some even only three forward, any block can start easily, shifting just to change the cruising speed, so it's with high speed, the engine for the most part with a plunger, speed is so low, reliable and durable degree still use to say? In turn, the chain machine under the condition of the commonly used high speed several times, want to do the same durable, is that possible????? The answer is yes, however, on the material, technology, the high precision requirement is too much, of course the cost would be much higher.
