what is a 2zz engine?

The 2ZZ-GE was the first production engine to combine cam-phasing variable valve timing with dual-profile variable valve lift in the American market. ... Toyota commissioned Yamaha to design the 2ZZ-GE, based on Toyota's ZZ block, for high-RPM operation and producing a power peak near the top of the RPM range.

More shifting. Because the two-stroke dirt bike engine operates on just two strokes to complete an engine cycle, it produces more power per stroke.

2H. The 2H is a 4.0 L (3,980 cc) inline 6, 12 valve OHV indirect injection diesel engine. Bore is 91 mm and stroke is 102 mm, with a compression ratio of 20.7:1.

A three-pulse fuel injection mode has been studied by implementing two-input-two-output (2I2O) control of both peak combustion pressure (Pmax) and indicated mean effective pressure (IMEP).

However, due to strict modern emission norms, two-stroke motorcycles were deemed obsolete soon, and the RX100 bit the dust. A two-stroke engine produces power in half the number of piston strokes that a four-stroke motor would require.

The 2JZ-GTE is an inline-layout, six-cylinder, belt-driven dual overhead camshaft, air-intercooled, twin-turbocharged, cast-iron block, aluminium cylinder headed engine designed and manufactured by Toyota Motor Corporation that was produced from 1991 until 2002 in Japan.

A four-stroke engine (also known as four-cycle) is an internal combustion engine in which the piston completes four separate strokes which comprise a single thermodynamic cycle. A stroke refers to the full travel of the piston along the cylinder, in either direction.

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.

Engine. The engine is a 300+ bhp 2 L turbo-charged direct injection unit using fly by wire throttle control. It is intended to have a low cost to develop, build, buy and maintain. Teams can decide whether build their own unit to the spec, or teams can lease/purchase a TOCA-BTCC engine ready built.

The easiest way to determine if your small engine is a 2-cycle or 4-cycle is the number and type of fill ports (where you add either oil or gas) on the engine. ... If the engine has two fill ports, one for gas and another separate one for oil, you have a 4-cycle engine. Do NOT mix oil and gas in these engines.

Because 2-stroke engines are designed to run at a higher RPM, they also tend to wear out faster; a 4-stroke engine is generally more durable. That being said, 2-stroke engines are more powerful. Two-stroke engines are a much simpler design, making them easier to fix. They do not have valves, but rather ports.

"Typically, 2-stroke engines rev up to higher speeds than 4-stroke engines, and this accounts for much of the higher power per pound," Parish says. "Also, small 2-stroke engines use intake and exhaust ports instead of valves, thus saving the weight and cost of a valve train.

Anti-lag is a system that is used to keep a turbo spooled when you lift off the throttle. ... Anti-lag is only used on turbocharged engines. Two step is a secondary rev-limiter that holds a set RPM to get the best launch. This can be done through ignition cut, fuel cut, or the ECU with a button.

Specification: Mode of Engine: Single cylinder, air-cooling, 2-stroke. Bore & Stroke: 47mm X 40mm=80 cm3. Rated Power: 2.5Kw/5000r/min (3 horsepower/5000r/min)

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.

The word 2x is used in Texting meaning two times,twice,double.
