The oil is dyed blue to make it easier to recognize in the gasoline. It appears black in this bottle because it is not diluted. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline-powered engines.
The engine displaced 4.5 L (4,477 cc) with a bore and stroke measuring 100 mm × 95 mm (3.94 in × 3.74 in), respectively and a 9.0:1 compression ratio; the head used Toyota's narrow-angle overhead camshafts for better fuel economy. [1] The 1FZ had only two variants available: the 1FZ-F and the 1FZ-FE.
A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...
[citation needed] This engine was used in Benz racing cars, produced 20 hp (15 kW), had a displacement of 5.4 L (330 cu in) and was designed by Georg Diehl. London company Wilson-Pilcher released its first car in 1901, which was powered by a flat-four engine. This engine was mounted longitudinally in the chassis, water-cooled, produced 9 hp (7 ...
The gross power and torque outputs decreased to 72 hp (54 kW; 73 PS) and 112 lb⋅ft (152 N⋅m), respectively, when the engine had a 6.9:1 compression ratio. Bore and stroke dimensions were the same as the L-head engine at 3 + 1 ⁄ 8 x 4 + 3 ⁄ 8 inches, giving 134.2 cu in (2,199 cc). [3] The F4-134 was introduced in 1950 in the Jeep Truck. [4]
The 1.2-litre engine is called Type 122 and has a displacement of 1,192 cc (72.7 cu in). [3] As industrial engine, its rated power is 22.8 kW (31 PS; 31 bhp) at 3000 min −1 without a governor , the highest torque 81.4 N⋅m (60 lbf⋅ft) at 2000 min −1 .
The F4 engine is a liquid cooled inline four cylinder four-stroke set across the frame with two overhead camshafts , 16 'radial' valves, electronic multipoint fuel injection, and induction discharge electronic ignition having engine displacements of 749.5 cc (45.74 cu in), 998 cc (60.9 cu in), and 1,078 cc (65.8 cu in).
Over the course of 2021, many Formula 4 championships announced their intent to use the car in the 2022 season: the Italian F4 Championship, [7] F4 British Championship, [8] F4 Spanish Championship, Formula 4 UAE Championship, F4 Brazilian Championship, ACCR Formula 4 Championship and ADAC Formula 4. The car first began testing in September ...
