The research and development of Yuchai engine has a certain foundation. Yuchai engine runs well with low fuel consumption. Compared with imported engines, Yuchai engine also has certain advantages.
Yuchai diesel engine adopts integrated cylinder head design, and the cylinder head integrates the intake pipe, which makes the structure more compact. TOP DOWN technology, the cooling liquid flows into the cylinder block for cooling, with large cooling liquid flow and higher cooling efficiency, which solves the problem of high heat load of natural gas engine. In this technology, Yuchai can be said to be at the forefront of the diesel engine industry. In addition, it is also exported to South Asia, Africa, Central Asia and other regions. We all know that the temperature in those areas is very high all the year round, and Yuchai pumping unit can just solve this problem of easy heating.
DPCI engine produced by Yuchai diesel engine has the characteristics of high efficiency, light weight, low emission and low energy consumption. Among them, DPCI's new product is fully electronically controlled Type 4 locomotive, which has the following advantages in use:
1, outstanding power performance. Although Yuchai oil press is in the initial stage of research and development, the diesel engine power is insufficient when the machine climbs the slope, which is very difficult. But with the continuous efforts of engineers, they can solve this problem well in the later improvement and upgrade the power to a higher level.
2. The thermal efficiency is higher than that of the original engine, and the price of natural gas is lower than that of diesel, so the economic benefit is obvious.
3, the reliability is high, some special faults of the gas engine are reduced, and the lubrication function of the diesel engine is maintained. The valve and seat wear of DPCI engine is much less than that of pure gas engine, and the heat load is the same as that of the original engine.
Fourth, there is no ignition system, so the maintenance cost is low.
