Ten years ago, China’s leading manufacturer of commercial vehicles – Shaanxi Auto Holdings and global power leader – Cummins work together to set up 50:50 ratio of joint venture Xi’an Cummins Engine Co., Ltd., introducing Cummins ISM heavy-duty flagship engine into China, achieving successful realization of local production. Over the past decade, as heavy-duty diesel engine model, ISM series has …

Diesel Engine exhaust white smoke is not fully atomized and burned fuel particles or water vapor, not atomized fuel or water into the cylinder will make the exhaust white smoke. The main reasons are the followings: 1. Low temperature and insufficient cylinder pressure, poor fuel atomization, especially initial period of the cold start; 2. Cylinder gasket damage, cooling water into …

1) Core business Cummins will continue to focus on its core business markets – engines, power system, spare parts and distribution services. Our success in core business are common, such as Cummins’ largest engine platform – QSK95; the latest release of X15 series engines offering the best fuel economy and maintenance costs at the same level. This engine uses parts …

The black smoke in the exhaust gas is mainly the carbon particles of incomplete combustion. Incomplete fuel combustion will be caused by over-supply fuel of the fuel supply system, reduced amount of air in air intake system, poor sealing of combustion chamber composed of cylinder block, cylinder head and the piston, poor fuel injector and other factors, so black smoke …

First check if there is factory certificate and product certification, they are the diesel engine factory “proof of identity”, which is necessary. And then check the three numbers on the certificate: 1) nameplate number; 2) engine body number ( generally on the plane of mechanical processing on the flywheel end, the font is convex); 3) pump nameplate number. Check the …

1. Enough cooling water. 2. Thermostat If the thermostat can not open the shutter in time, you must promptly replace it, and if it can not be timely replaced, the thermostat can be temporarily removed, never put the faulty thermostat on the outlet. 3. Pay attention to the reading of water temperature meter, not more than 95 Celsius. In special …

The vehicle suddenly becomes underpowered in the process of driving , which not only cause unnecessary fuel consumption, also delay schedule. There are many reasons for the sudden lack of power, two aspects are introduced here mainly from the air and oil channel. 1. Fuel filter clogged, injector wear The main role of fuel filter is to remove debris in …

6. Lax piston ring sealing and cylinder leakage result in too large crankcase ventilation, and the oil is expelled out with the ventilation, which will lead to high oil temperature. Regularly check the piston ring and cylinder seal to avoid leakage, once occurred, replace or repair in time. 7. Too large bearing gap and too much leaking oil result in …

1. Insufficient oil or high liquid level causes the oil temperature to be too high. To ensure adequate engine running oil, to ensure the oil level on the scale line of oil scale in the routine maintenance process. 2. Oil pump failure and insufficient pump oil result in insufficient oil pressure and poor heat dissipation. Pay close attention to oil …

At the first day of Beijing Road Transport Vehicle Show on May 23, 2016, Cummins showed the industry the environmental potential of traditional energy and alternative energy sources with a new generation of “Near Zero Emission” forward technology. Through Smart Efficiency (passenger vehicle power solution), Cummins not only achieves near zero emissions in terms of emission reductions, but also achieves …
