The Mercedes-Benz M278 [1] is a family of direct injected, Bi-turbocharged, V8 gasoline automotive piston engines.. The M278 is derived from the company's previous M273 V8 engine, sharing its bore pitch, aluminium engine block, and Silitec aluminium/silicon low-friction cylinder liners. [2]
The M176/M177/M178 is a petrol V8 engine range designed by Mercedes-AMG, replacing the M278 and M157 engines, and is based on the M133 engine. [1]The engine has two BorgWarner turbochargers positioned between the two cylinder heads in a "hot-V" configuration.
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 crank sensor (CKP) [1] [2] [3] is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.
The two numbers between the first and second letters denote the displacement of the engine in liters. The suffix denoting the features of the engine is still used, as with prior engines. Examples: M20A-FKS M20A is a 2.0-liter engine, as denoted by the "20" in "M20A" F – Normal cylinder head DOHC; K – On-demand Atkinson cycle in non-hybrid ...
These 2.9L (biturbo) & 3.0L (single turbo) V6 engines share the 4.0T TFSI V8's "hot vee" design, meaning the turbo(s) are placed in the Vee of the engine (between each bank of cylinders) instead of on the outside of each cylinder bank.
A deep-cycle battery powering a traffic signal. A deep-cycle battery is a battery designed to be regularly deeply discharged using most of its capacity. The term is traditionally mainly used for lead–acid batteries in the same form factor as automotive batteries; and contrasted with starter or cranking automotive batteries designed to deliver only a small part of their capacity in a short ...
In 1999, the Range Rover V8 received a new Bosch Motronic engine management system from the BMW 7 Series (E38).This replaced the Lucas "SAGEM" GEMS system. This engine is also known as the Bosch or Thor engine the later engine also featured revised engine mounts along with a structural alloy sump to stiffen the engine up to help improve refinement and prevent vibration ingress into the cabin.
