The engine's timing components are located at the rear of the engine, and feature timing chains to drive the camshafts and high pressure fuel pump, and a wet belt to drive the oil pump. [ 1 ] Most of the development and engineering work for the LM2 Duramax, as well as primary calibration took place in Turin , Italy.

The system adjusts both intake and exhaust timing between two settings. This engine produces 403 hp (301 kW) and 417 lb⋅ft (565 N⋅m) in the GMC Yukon Denali/XL Denali, GMC Sierra Denali, Hummer H2, and briefly in the Chevrolet Tahoe LTZ (MY 2008.5 – MY 2009) and rated at 403 hp (301 kW) and 415 lb⋅ft (563 N⋅m).
The Yukon XL officially went on sale for the first time ever in Mexico, starting in the Fall of 2020 with the 2021 models (GMC had only offered the Yukon in that country because GM did not want to have the Yukon XL cannibalized in terms of sales with the Suburban, which is also that country's best-selling SUV), where it is only available in the ...
It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy. Estimated performance on EPA tests shows a 5.5–7.5% improvement in fuel economy. [1] GM's Active Fuel Management [2] technology used a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine.
A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
The 1992–93 LT1s used speed density fuel management, batch-fire fuel injection and a dedicated Engine Control Module (ECM). In 1994 the LT1 switched to a mass airflow sensor and sequential port injection. A new, more capable computer controlled the transmission as well as the engine and got a new name: Powertrain Control Module (PCM). Where ...
Magnetoresistance type fuel level sensors, now becoming common in small aircraft applications, offer a potential alternative for automotive use.These fuel level sensors work similar to the potentiometer example, however a sealed detector at the float pivot determines the angular position of a magnet pair at the pivot end of the float arm.
