Any non-combustible materials found in lubrication additives will remain in the DPF, which can cause problems with back pressure and efficiency. This means the DPF needs to be regularly removed and cleaned for the Cummins ISX. An ash-less oil could mean that cleaning would be unnecessary, but can inhibit lubrication properties.
Particles in the oil can also cause serious problems with oil pressure. After oil flows through the engine, it returns to the oil pan, and can carry along a lot of debris. The debris can cause problems with the oil pickup screen and the oil pump itself. The holes in the oil pickup screen measure about 0.04 square inches (0.26 cm 2). [6]
Crankcase dilution is a phenomenon of internal combustion engines in which unburned diesel or gasoline accumulates in the crankcase.Excessively rich fuel mixture or incomplete combustion allows a certain amount of fuel to pass down between the pistons and cylinder walls and dilute the engine oil.
Also Cummins PT (pressure-time) is a form of unit injection where the fuel injectors are on a common rail fed by a low-pressure pump and the injectors are actuated by a third lobe on the camshaft. The pressure determines how much fuel the injectors get and the time is determined by the cam.
Despite that limitation, the 12 litre Cummins Westport ISX12G engine [49] is an example of a CNG capable engine designed to pull tractor/trailer loads up to 36 tonnes (80,000 lb) showing CNG can be used in most if not all on-road truck applications. The original ISX G engines incorporated a turbocharger to enhance the air-fuel energy density. [50]

From E. coli traced to slivered onions on McDonald's Quarter Pounders to mass recalls of frozen waffles due to listeria risk, foodborne illness seems ever-present in the headlines.
The typical compression brake consists of a hydraulic system using engine oil which transfers the motion of the fuel injector rocker arm to the engine's exhaust valve(s). When activated, the exhaust valve opens very briefly near the engine's top dead center , and releases the compressed air in the cylinder so that the air compression energy is ...
