Detailed Information
Technology Function
Single overhead camshaft with roller rocker The short driving chain makes the valve control more accurate. The friction pairs are reduced in number, with little change in the valve clearance. The E series bus diesel engine works reliably.
Compression release braking Large braking power, rational structure layout, zero influence to the height of the engine
Cracking connecting rod Automatic error proofing, reliable performance and precise positioning
Rear gear housing with PTO output Reduce the noise of vibration and widen the application scope
Two standard oil filters in parallel Decrease maintenance cost and it is easy to get accessories
Optional bypass oil filter The oil replacement cycle is prolonged by over 50%.

Features
1.Strong Power
The E series bus diesel engine is prepared with large torque reserved and sufficient power so that it works smoothly without power loss at the altitude of 2500m on the plateau. It enables the vehicle to run with strong power and overload capacity.

2. Energy Conservation and Environmental Protection
It offers efficient fuel combustion and low friction. The minimum fuel consumption is about 185g/kw.h, consistent with the international advanced level. This product makes full use of every drop of fuel and its emission meets the standards of China III, IV and V. It saves the energy over protecting the environment.

3. Efficient Braking
This engine is configured with the progressive compression braking system that offers 21kw/l braking power at the speed of 1900 rpm. While the vehicle with heavy load drives downhill, this system keeps the safety and reduces the fatigue of the driver. Moreover, it significantly decreases the wear of the brake facing. At idling state, the engine generates low noise and vibration.

4. Reliability and Durability
The general service life of the E series bus diesel engine is about 1 million kilometers. Under the standard operating conditions, the interval for adjusting the valve clearance is extended to 40,000 km and the engine oil will be changed after running for 40,000 km.

5. Intelligent and Convenient Performance
This product functions cruise control, relaxed driving, GPS positioning and remote diagnosis. Users can have a direct contact with the modern electronic communication technology.

6. Easy Maintenance
In the range of 40,000 km, there is no need to adjust the clearance. Moreover, this E series bus diesel engine adopts the easily detachable and repairable accessories and other spare parts like oil filter are the sophisticated products commonly applied in the market.
