Vehicles using Atkinson-cycle engines
  • Chevrolet Volt.
  • Chrysler Pacifica (front-wheel drive) plug-in hybrid model minivan.
  • Ford C-Max (front-wheel drive / US market) hybrid and plug-in hybrid models.
  • Ford Escape/Mercury Mariner/Mazda Tribute electric (front- and four-wheel drive) with a compression ratio of 12.4:1.

Why do hybrids use Atkinson cycle engines?

The Atkinson cycle is ideal for hybrids because their electric motor(s) make up for the lost low-speed output. ... In most engines, the compression ratio is set as high as the engine can stand short of detonation in pursuit of power and efficiency. Compression and expansion ratios are the same in an Otto engine.

Why does Toyota use Atkinson cycle engines?

The final return stroke of the cycle evacuates the spent gases via the exhaust valve so that the process can begin again. ... This revelation allowed Toyota to build the world's first Otto cycle engine with a simulated Atkinson-type valve action to significantly improve fuel efficiency.

Who makes Atkinson engines?

Honda engineers update an established engine design with leading-edge technology to create an extremely fuel-efficient powerplant. The Feature: The CR-V Hybrid engine makes for excellent efficiency as well as responsive power output.

What is the difference between Miller and Atkinson cycle?

An Atkinson-cycle engine differs from a Miller-cycle engine in that the Miller-cycle engine uses some device to push air into the system – a supercharger or turbocharger – while the Atkinson-cycle engine is naturally aspirated.

What does the Atkinson cycle consist of?

The ideal Atkinson cycle consists of: 1–2 Isentropic, or reversible, adiabatic compression. 2–3 Isochoric heating (Qp) 3–4 Isobaric heating (Qp')

What is Toyota Atkinson cycle?

Atkinson cycle engines employ an additional linkage that will allow the air intake valve to stay open longer, creating a shorter and more complete compression stroke. This ensures that the new Tacoma 3.5-liter Atkinson cycle V-6 engine will maximize power and efficiency.

What is the difference between Otto cycle and Atkinson cycle?

An Atkinson cycle has a greater work output and a higher thermal efficiency than the Otto cycle at the same operating condition. The compression ratios that maximize the work of the Otto cycle are always found to be higher than those for the Atkinson cycle at the same operating conditions.

How much more efficient is the Atkinson cycle?

The end result is a maximum thermal efficiency of 37 percent and a fuel efficiency improvement of "approximately 30 percent over current vehicles" – that's the difference between 60 mpg (US) and 78 mpg (US) and it's an astonishing improvement.

What type of IC engine is used in Toyota Prius?

The Prius has a 1497 cubic centimetre (approximately 1.5 litre) displacement gasoline internal combustion engine which produces all power for the car.

Who invented the Atkinson-cycle engine?

A thermodynamically more efficient version of modern Otto-cycle engines, the Atkinson-cycle engine was invented way back in 1887 by British engineer James Atkinson. As a refresher, a standard Otto-cycle engine operates in four strokes: the intake, compression, power/expansion and exhaust stroke.

What is the disadvantage of a hybrid car?

The biggest drawback of having a hybrid car is that it can burn a hole in your pocket. Hybrid cars are comparatively expensive than a regular petrol car and can cost $5000 to $10000 more than a standard version. However, that extra amount can be offset with lower running costs and tax exemptions.

What is meant by Otto cycle?

An Otto cycle is an idealized thermodynamic cycle that describes the functioning of a typical spark ignition piston engine. ... The Otto cycle is a description of what happens to a mass of gas as it is subjected to changes of pressure, temperature, volume, addition of heat, and removal of heat.

What are the different engine cycles?

The cycle includes four distinct processes: intake, compression, combustion and power stroke, and exhaust.

How many engine cycles are there?

The Four-Stroke Cycle

The internal combustion engines that power many of today's cars and trucks typically run on a four-stroke cycle, and those four stages are intake, compression, combustion, and exhaust.

Is there a V24 engine?

A V24 engine is a 24-cylinder piston engine where two banks of twelve cylinders are arranged in a V configuration around a common crankshaft. The majority of V24 engines, however, have been "dual V12" engines where two separate V12 engines are placed in line with each other.
