The Alfa Romeo Twin Cam engine is an all-alloy inline-four engine series produced by Alfa Romeo from 1954 to 1994. In Italian it is known as the "bialbero" ("twin-shaft"), and has also been nicknamed the "Nord" (North) engine in reference to its being built in Portello, Milan (later Arese, close to Milan), in the North of Italy and to distinguish it from the Alfa Romeo Boxer engine built in ...
The Lexus LF-A V10 engine Toyota-Yamaha Lexus LF-A Production Prototype engine 2009 Tokyo Motor Show. Announced in the Lexus LFA sports car, the 1LR-GUE is a 4,805 cc (4.8 L; 293.2 cu in) DOHC 4 valves per cylinder V10 engine, made from aluminum alloy, magnesium alloy and titanium alloy and is smaller than most V8s.
The weight of these petrol engines made of die-cast aluminium is only 97 kg (214 lb) for the 1.2 TSI and 106 kg (234 lb) for the 1.4 TSI. The crankshaft alone became lighter by 20 per cent; the connecting rods lost 30 per cent of their weight.
The 360 used the large intake port 340 heads with a smaller intake valve of 1.88 in (48 mm). In 1974, with the introduction of the code E58 4-barrel dual-exhaust version, at 245 hp (183 kW) SAE net, it became the most powerful LA engine with the end of 340 production. Power started dropping from 1975 on as more emission controls were added ...

The L24 was a 2,393 cc (2.4 L; 146.0 cu in) engine produced from 1969 through 1984. Like the L20A, it was based on the design of the L16. Like the L20A, it was based on the design of the L16. It produces 130 PS (128 bhp; 96 kW) and the version with twin side draught SU Carburettors produces 150 PS (148 bhp; 110 kW).
When describing a crankshaft design, the number of main bearings is generally quoted, as the number of crank pins is determined by the cylinder layout. For example, the Toyota VZ V6 engine is described as having a "four bearing crankshaft" and the Jaguar XK6 straight-six engine has a "seven bearing crankshaft".
The block was taller than that of the 3.5-liter 6G74. The pistons were high-pressure castings, joined to forged steel connecting rods and a heat-treated, forged steel crankshaft. [5] Intended to be used with 95 RON fuel, lower octane fuels would be detected by the vehicle's knock sensors, and the engine detuned to compensate.
