The emissions control system will institute a filter regeneration which burns off the particulates. 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.
The Cummins L-series engine is a straight-six diesel engine designed and produced by Cummins. It displaces 8.9 litres (543.1 cu in), and began production in 1982 as the L10 at the Jamestown Engine Plant in Jamestown, New York. After lengthening its stroke from 136 to 147 mm, its displacement was enlarged to 10.8 litres and the engine renamed ...
The Cummins M-series engine is a straight-six diesel engine designed and produced by Cummins.It displaces 10.8 litres (659.1 cu in).Introduced as the M11 in 1994, it was built on the previous L10 engine (same 4.921 inches (125.0 mm) cylinder bore, but a longer 5.787 inches (147.0 mm) piston stroke compared to the L10's 5.354 inches (136.0 mm) stroke).
In contrast, a gasoline engine under deceleration runs with a closed throttle that prevents free flow of air into the cylinders, resulting in little pressure to release at the top of the compression stroke. The closed throttle provides engine braking by forcing the engine to generate a vacuum between the throttle and the cylinders.
The Cummins ISC also has a sister engine which is designed off the existing ISC 8.3-litre cylinder block which runs on compressed natural gas (CNG). Cummins reintroduced this engine as the C PLUS engine which has a maximum power rating of 280 horsepower (209 kW; 284 PS). A few thousand units of this engine are now roaming in the world operating ...
The introduction of the Cummins Turbo Diesel model in 1989 coincided with the first sales increase for Ram trucks in several years. The Cummins was coupled with a heavier-duty version of the A727 automatic or a 5-speed manual transmission and was available on 250 and 350 pickups and pickup-based chassis-cab trucks above 8,500 pounds GVWR.
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.
For the 2003 model year, the Cummins was introduced with Bosch high pressure common rail fuel injection, again increasing power output. On automatic equipped vehicles, the 47RE was upgraded internally to increase durability and torque capacity, now known as the 48RE. The 2003 rating for the Dodge truck was released at 305 hp (227 kW; 309 PS ...
