Published:2011/5/20 11:06:00 Author:Borg | Keyword: oil injection system, Tianjin Xiali

The TJ376Q-E electric controlled oil injection system belongs to a speed-density(D) oil multiple points injecting engine, whose main ingredients are as shown in Figure 5-1. Like other petrol injecting engine, it consists of admission system, oil supply system and electric control system.1.admission systemThe air comes through the filter(5) to remove the dust, and then goes past the throttle body(11) and the throttle and into the balance box(15) where it is re-distributed into each admission cylinder. When the admission valve is open, the air is inhaled into the cylinder with the petrol.   (View)

The circuit of Tianjin Xiali TJ710OE

Published:2011/5/20 3:41:00 Author:Borg | Keyword: circuit, Tianjin Xiali

The new EFI of Tianjin Xiali started to be produced by DAZE Automobile Industry in 1997, it improved on 710OU. In TJ710OE, the engine is the TJ376Q-E e-control petrol injection engine,and the 710OU is fixed with the TJ376Q carburetor engine. After a lot of times of trials, we finally succeeded, and the car war launched to the market. The outline of the car has been improved, but the body and the chassis are almost the same with the former model. It it three-box, four-door and five-chairs, the maximum speed is more than 140km/h, the oil consumption at stable speed(60km/h) is less than 4.2L which is conforming to ECEl5-04. In a word, all the indexes are better than the former TJ710OU and TJ7100.   (View)
