The Honda EXP-2 was an off-road experimental prototype motorcycle, designed in 1995, with a fuel injected 400 cc (24 cu in) two-stroke engine. It was intended to serve global markets that still relied heavily on two-stroke technology, but to comply with increasingly strict emissions laws.
With the utilization of a redesigned exhaust port valve and the ARC (Activated Radical Combustion) system engaged, the engine would produce a pre-ignited combustion effect at low throttle that would completely burn all fuel in the chamber compared to how a conventional two-stroke engine would lose part of the intake charge. [1] The result decreased two major drawbacks of two-stroke technology of both incomplete combustion of fuel at low engine revolutions (RPM) and expulsion of unburned fuel at high RPM.
CVCC, or Compound Vortex Controlled Combustion, is an internal combustion engine technology developed and trademarked by the Honda Motor Company.
VTEC is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM. The VTEC system uses two camshaft profiles and hydraulically selects between profiles. It was invented by Honda engineer Ikuo Kajitani. It is distinctly different from standard VVT systems which change only the valve timings and do not change the camshaft profile or valve lift in any way.
Variable valve timing (VVT) is the process of altering the timing of a valve lift event in an internal combustion engine, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing many automotive manufacturers to use VVT systems.
Redline refers to the maximum engine speed at which an internal combustion engine or traction motor and its components are designed to operate without causing damage to the components themselves or other parts of the engine. The redline of an engine depends on various factors such as stroke, mass of the components, displacement, composition of components, and balance of components.
Reed valves are a type of check valve which restrict the flow of fluids to a single direction, opening and closing under changing pressure on each face. Modern versions often consist of flexible metal or composite materials.
The E-series was a line of inline four-cylinder automobile engines designed and built by Honda for use in their cars in the 1970s and 1980s. These engines were notable for the use of CVCC technology, introduced in the ED1 engine in the 1975 Civic, which met 1970s emissions standards without using a catalytic converter.
The Honda Super Cub is a Honda underbone motorcycle with a four-stroke single-cylinder engine ranging in displacement from 49 to 124 cc.
Homogeneous charge compression ignition (HCCI) is a form of internal combustion in which well-mixed fuel and oxidizer are compressed to the point of auto-ignition. As in other forms of combustion, this exothermic reaction produces heat that can be transformed into work in a heat engine.
The Honda F-Series engine was considered Honda's "big block" SOHC inline four, though lower production DOHC versions of the F-series were built. It features a solid iron or aluminum open deck cast iron sleeved block and aluminum/magnesium cylinder head.
The two-stroke power valve system is an improvement to a conventional two-stroke engine that gives a high power output over a wider RPM range.
A motorcycle engine is an engine that powers a motorcycle. Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used.
Stroke ratio, today universally defined as bore/stroke ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length in a reciprocating piston engine. This can be used for either an internal combustion engine, where the fuel is burned within the cylinders of the engine, or external combustion engine, such as a steam engine, where the combustion of the fuel takes place outside the working cylinders of the engine.
The Honda NR was a V-four motorcycle series started by Honda in 1979 with the 500cc NR500 Grand Prix racer which used oval pistons. This was followed during the 1980s by a 750cc endurance racer version known as the NR750. The oval piston concept allowed for eight valves per cylinder which generated more power due to the increased air/fuel mixture and throughout compression. In 1992 Honda produced around 300 street versions of a 750 cc model, the NR, with a 90-degree V angle. Whereas the NR500 had used an oval piston with straight sides, the road going NR750 used an elliptical piston with curved long sides. The bike became the most expensive production bike at the time, selling for $50,000.
The Honda CBR1000RR, marketed in some countries as the "Fireblade", is a 999 cc (61.0 cu in) liquid-cooled inline four-cylinder superbike, introduced by Honda in 2004 as the 7th generation of the CBR series of motorcycles that began with the CBR900RR in 1992.
The Yamaha YZ450F is a four-stroke racing motocross bike built by Yamaha Motor Corporation. It was the successor to the previous YZ426F which was discontinued in 2003. It is credited by Cycle World and Dirt Rider magazines as the bike that started the four-stroke dirt bike revolution. The 2006 YZ250F and YZ450F were the first production motorcycles equipped with titanium suspension springs.
Two- and four-stroke engines are engines that combine elements from both two-stroke and four-stroke engines. They usually incorporate two pistons.
The E0 series is a three-cylinder gasoline engine developed and manufactured by Honda, with a total displacement of 656 cc. The engine is intended for kei car applications. The E05A and E07A were partially replaced by the Honda P engine but as of 2020 the E07Z engine still saw use in the Acty truck.
Dual Ignition is a system for spark-ignition engines, whereby critical ignition components, such as spark plugs and magnetos, are duplicated. Dual ignition is most commonly employed on aero engines, and is sometimes found on cars and motorcycles.
An internal combustion engine is a heat engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons, turbine blades, a rotor, or a nozzle. This force moves the component over a distance. This process transforms chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to.
The five-stroke engine is a compound internal combustion engine patented by Gerhard Schmitz in 2000.
