2 stroke what it means?
312136
A two-stroke (or two-cycle) engine is a type of internal combustion engine which completes a power cycle with two strokes (up and down movements) of the piston during only one crankshaft revolution.

The 2V stands for, as it does most usually, 2 venturis, and describes a two barrelled carburettor. American 2V 351Clevelands came equipped with two barrelled carbs and as such the engine was designed to be the common version of the engine fitted to non performance cars.

Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines.

A "barrel" is American slang for a venturi or choke. A "two Barrel" is a twin venturi or twin choke carburetor. Both barrels open at the same time. They are small and are usually used on the smaller engines. A 4 barrel carb has one half the same as the 2 barrel.

Typically, a 2-stroke engine creates more torque at a higher RPM, while a 4-stroke engine creates a higher torque at a lower RPM. ... Four-stroke engines have more parts, therefore they are more expensive and repairs cost more. Two-stroke engines require pre-mixing of oil and fuel, while the 4-strokes do not.

Two-stroke engines making comeback. Two-stroke engines were phased out by tough pollution laws and fuel economy targets, but they could be making a comeback with KTM, Honda and boutique builders. KTM and Honda have both registered patents for direct-injection two-stroke engines.

The two stroke engine is the main reason why PWC's are being banned around the nation. ... The combination of light weight and twice the power gives two-stroke engines a great power-to-weight ratio compared to many four-stroke engine designs.

These days we refer to a 2 valve head as any head that has two valves per cylinder and a 4 valve head as any that has four valves per cylinder, and these sometimes get written as 2V and 4V for short, but should not be confused with the old defintions.

Overall, a two-stroke engine contains two processes: Compression stroke: The inlet port opens, the air-fuel mixture enters the chamber and the piston moves upwards compressing this mixture. A spark plug ignites the compressed fuel and begins the power stroke.

A 2-stroke engine relies on both the cylinder and crankcase to make this happen. ... For its part, a 4-stroke engine requires four strokes of the piston to complete a power cycle. The four strokes are intake, compression, power and exhaust.

A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction.

The difference between a 2-cycle engine and 4-cycle engine is the 2-cycle only needs one revolution of the crankshaft to get to a power stroke, while a 4-cycle engine needs 2 revolutions. ... A two-cycle engine piston has only two strokes. The piston starts at top dead center (TDC) in its bore.

This isn't a hot 4 stroke we're are talking about here, 2 stroke engines are very easy to start hot or cold, and hard starting is a sign that something is not right in your engine. All that kicking or pulling is just wearing out your starter and probably your leg or arm in the process.

7.3 Power Stroke. ... The Power Stroke is an electronically controlled, direct injection engine with a 4.11 in × 4.18 in (104.4 mm × 106.2 mm) bore and stroke creating a displacement of 444 cu in (7.3 L). It has a 17.5:1 compression ratio, and a dry weight of approximately 920 lb (417 kg).

Two-stroke (two-cycle) engines require you to mix the oil with the gas in exact amounts so the oil acts as a lubricant for the crankcase, while four-stroke engines take oil and gas separately. ... In a 4-stroke engine, it takes two revolutions (4 stages) to complete 1 power stroke.

It is the output power of the motor. So a 2 hp motor is capable of delivering a power output of 2 x 746 watts.

It is called a “2-stroke” because just one up and down movement of the piston—the 2 strokes—performs the full cycle of intake, compression, combustion and exhaust.
