Which is the world's biggest engine??????

Answer 1

Would be the type used on large ocean going ships, yes. Like the Wartsila-Sulzer RTA96-C Take a look at the link.

Answer 2

Pushrod engines are the biggest engines in the world, whatever the automobile may be, the engine size would be proportional...

A pushrod engine or I-head engine is a type of piston engine that places the camshaft in the cylinder block (usually beside and slightly above the crankshaft in a straight engine or directly above the crankshaft in the V of a V engine) and uses pushrods or rods to actuate rocker arms above the cylinder head to actuate the valves. Lifters or tappets reside in the engine block between the camshaft and pushrods.

This contrasts with an overhead cam (OHC) design which places the camshafts above the cylinder head and drives the valves directly or through short rocker arms. In an OHC engine, the camshafts are normally part of the cylinder head assembly, while in an I-head engine the camshaft (rarely more than one) is part of the main engine block assembly.

Pushrod engines are perceived to be "old fashioned" by the modern automotive press, the cause is historical: While both layouts are over 100 years old, the I-head engine came first. OHC engines were developed as more expensive high-performance engines and have largely replaced the pushrod design in countries where cars are taxed based on engine displacement. In 1949, Oldsmobile introduced the Rocket V8. It was the first high-compression I-head design, and is the archetype for most modern pushrod engines. Currently General Motors is the world's largest pushrod engine producer with engines such as the 3800 Series III Supercharged V6 (260 hp, 280 lb/ft torque), LS7 Corvette 7.0L V8 Engine (505 hp, 475 lb/ft torque) and LS4 5.3L DOD V8 (303 hp, 323 ft·lbf torque). Currently few pushrod type engines remain in production, a result of the fact that it has become difficult to achieve competitive engine performance with the configuration.

Answer 3

Its the 14 cylender Diesel on some container ships. The largest iteration is 2300 tons, 89 feet long, and 44 feet tall. Gives off over 5.6 million foot-pounds of torque at a whopping 102 RPM. Its a 25,480 liter engine.

Answer 4

The Wartsila NSD (Sulzer) RTA96-C two-stroke diesel engine
is the most powerful and most efficient piston prime-mover in the world today.
Bore - just under 3'2" (965mm). Stroke - just over 8'2" (2489mm). Available in 6 through 12 cylinder versions (all inline). Engine weight exceeds 2000 tons in the 12 cylinder version (the crankshaft alone exceeds 300 tons). Point of maximum continuous power is 89,640 HP (66,844kW) at 100RPM with the 12 cylinder version. Point of maximum fuel economy is 53,244 HP(37,704kW)at 90 RPM.

The 12-cylinder engine exceeded 100,000 horsepower during overspeed testing (all of 101.5 RPM!) while under test at Japan's Diesel Union works (who built the first engines and from whmo these pictures are taken). Fuel consumption at maximum power is 0.278 lbs/HP/hour (BSFC). Fuel consumption at maximum economy is 0.260 lbs/HP/hour. At maximum economy the Sulzer engine exceeds 50% thermal efficiency: i.e. more than 50% of the fuel going into the engine is converted to power. For comparison, consider that automotive and small aircraft spark-ignition engines have British Standard Fuel Consumption figures in the 0.40-0.60 lbs/HP/hour range and 25-30% thermal efficiency. Even at its most efficient power setting, the Sulzer 12 cylinder consumes nearly 1,660 gallons of heavy fuel oil an hour.
