The Northstar engine is a family of high-performance 90° V engines produced by General Motors between 1993 and 2011. Regarded as GM's most technically complex engine, the original double overhead cam, four valve per cylinder, aluminum block/aluminum head V8 design was developed by Oldsmobile R&D, [citation needed] but is most associated with Cadillac's Northstar series.
A 2.0 L multi-point fuel-injected (KE-Jetronic) variation of the M102.921. An "E" was added to the model of the vehicle (standing for "einspritzung", the German word for fuel injection). This engine is identified by TSZ ignition and multiple belts for the alternator, power steering and air conditioning compressor (where fitted).
An ignition coil is used in the ignition system of a spark-ignition engine to transform the battery voltage to the much higher voltages required to operate the spark plug(s). The spark plugs then use this burst of high-voltage electricity to ignite the air-fuel mixture. The ignition coil is constructed of two sets of coils wound around an iron ...
This process is repeated continuously, creating a "shower of sparks." (Right) Booster coil components. The booster coil is separate from the magneto and can generate a series of sparks on its own. Current flow through the primary coil sets up a magnetic field about the coil that attracts the movable contact point, breaking circuit is broken.
The last variation of the LA series to be introduced before the Magnum upgrade was the 1988–92 throttle-body fuel injected, roller cam engine. The first engines to receive these modifications were the 318 cu in (5.2 L) V8 and 239 cu in (3.9 L) V6 engines.
This was so named because it began with Chevrolet's V8 engines. Chevrolet big-block V8s; Chevrolet small-block V8s; GM Vortec 4300 90° V6; GM Iron Duke RWD inline 4 (early RWD Variants, later versions may use a FWD pattern, and have two possible starter locations) Jeep with GM Iron Duke inline 4 2.5L/151 in 3 (1980-1983).
It features some of the latest engine technology such as direct fuel injection, sintered camshaft lobes, thin-walled engine block, variable valve timing and lift for intake and exhaust valves, downstream oxygen sensors, exhaust manifold integrated into the cylinder head, exhaust gas recirculation and cooling, distributors coil-on-plug ignition ...
Feuling later used a similar cylinder head design on what is reported to be a Cosworth block to create a Feuling/Oldsmobile V8 engine intended for Indianapolis. [15] This was a different engine than Oldsmobile's own Aurora IMSA/IRL racing V8. Output of the Feuling BE engine is estimated to have been approximately 1,000 hp (750 kW).
