The cylinder head was also redesigned to keep the compression ratio at 8.8:1 even with the flat top pistons and now featured provisions for an air injection reaction system. This engine was used from 1995 to 2002. [2] Some 1992 through 1998 L24 cylinder heads developed cracks in the fifth camshaft journal, located closest to #4 cylinder.
The Mitsubishi Saturn or 4G3 engine is series of overhead camshaft (OHC) straight-four internal combustion engines introduced by Mitsubishi Motors and saw first service in the 1969 Colt Galant. Displacement ranges from 1.2 to 1.8 L (1,239 to 1,755 cc), although there was also a rare 2-litre (1,994 cc) inline-six version built from 1970 until 1976.
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The majority of automotive four-cylinder engines use a straight-four layout [ 1 ] : pp. 13–16 (with the exceptions of the flat-four engines produced by Subaru and Porsche) [ 2 ...
General Motors plans to spend $483 million to upgrade a former Saturn engine plant in Spring Hill, Tenn., to build more four-cylinder Ecotec engines, the Detroit-based automaker said Friday. The ...
As with many even-firing engines with four or more cylinders, an even-firing four-cylinder engine is sometimes referred to as a "Screamer". A "long bang" inline 4 engine fires both pairs of cylinders in quick succession or simultaneously; the power delivery is identical to a parallel twin with a 180° crank and similar to a V-twin.
The S-IV stage was a large LOX/LH 2-fueled rocket stage used for the early test flights of the Saturn I rocket. It formed the second stage of the Saturn I and was powered by a cluster of six RL-10A-3 engines. Each one of the engines supplied 66.7 kilonewtons (15,000 lb f) of thrust for a total of about 400 kilonewtons (90,000 lb f).
The outgoing head of Ohio's troubled teachers retirement system said that she is leaving the fund in strong fiscal condition, despite the turmoil at the top that her successor will inherit. In a ...
Any inline engine with an odd number of cylinders has a primary imbalance, which causes an end-to-end rocking motion. As each cylinder bank in a V6 has three cylinders, each cylinder bank experiences this motion. [8] Balance shaft(s) are used on various V6 engines to reduce this rocking motion.
