Programmed Fuel Injection, or PGMFI/PGM-FI, is the name given by Honda to a proprietary digital electronic multi-point injection system for internal combustion engines. It has been available since the early 1980s. This system has been used in motorcycles, automobiles, and outboard motors.
With its origins beginning with the CX500 and CX650 turbocharged motorcycles in 1982 and 1983, respectively, Honda's PGM-FI made its way into their automobiles in the early 1980s with the ER engine equipped City Turbo. The system gained popularity in the late 1980s in their Accord and Prelude models with A20A, A20A3 & A20A4 engines (Honda A engine), and its motorcycles later on. In 1998, Honda built its third motorcycle with multi-point injection; the VFR800FI.
The PGM-FI system relies on a piezoelectric sensor to measure intake manifold air pressure, then combines that data with the crankshaft rpm and other info to compute the air quantity, and interprets the data using performance maps. Fuel is injected intermittently into the inlet ports. The PGM-FI also has a trailing throttle fuel cutoff and a self-diagnosis system. [1]
A stratified charge engine describes a certain type of internal combustion engine, usually spark ignition (SI) engine that can be used in trucks, automobiles, portable and stationary equipment. The term "stratified charge" refers to the working fluids and fuel vapors entering the cylinder. Usually the fuel is injected into the cylinder or enters as a fuel rich vapor where a spark or other means are used to initiate ignition where the fuel rich zone interacts with the air to promote complete combustion. A stratified charge can allow for slightly higher compression ratios without "knock," and leaner air/fuel ratio than in conventional internal combustion engines.
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.
The J-series is Honda's fourth production V6 engine family introduced in 1996, after the C-series, which consisted of three dissimilar versions. The J-series engine was designed in the United States by Honda engineers. It is built at Honda's Anna, Ohio, and Lincoln, Alabama, engine plants.
The Honda A series inline-four cylinder engine is used in 1980s Honda Accord and Prelude models. It was introduced in 1982, with the second-generation Honda Prelude, and available in three displacement sizes: 1.6-, 1.8- and 2.0-liters. It features cast iron block and aluminum SOHC head design with three valves per cylinder for a total of 12 valves. It was available in carbureted and fuel-injected configurations
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 Honda CBF1000 is a sport touring motorcycle, part of the CBF series produced by Honda from 2006 to 2018. It is powered by a 998 cc inline-four engine, which is based on the CBR1000RR Fireblade engine. The CBF1000 has a steel frame also based on the frame of another model, the CBF600. Produced by Honda Italia Industriale S.p.A., the CBF1000 was first available in March 2006, mainly in the European market.
The Honda CBR600F is a CBR series 600 cubic centimetres inline four-cylinder sport bike motorcycle made by Honda Motorcycles. The first model of the CBR600F was sold from 1987 to 1990 and is known in the US as the Hurricane. In Austria and Mexico, a smaller version, called CBR500F, was offered. The subsequent models are designated as CBR600F2, F3, F4, and F4i respectively. In 2011, Honda released a more modern model with the same name.
The Honda VTX series is a line of V-twin Honda cruiser motorcycles inspired by the Zodia concept shown at the 1995 Tokyo Motor Show. The Honda VTX 1800 was launched in 2001 as a 2002 model. At the time this bike was introduced the Honda VTX engine was the largest displacement production V-twin in the world, but that distinction would be short-lived as the VTX1800 was superseded in 2004 by the 2.0-litre Kawasaki Vulcan 2000. Nevertheless, the VTX 1800 still produced better 0-60 mph and 1/4 mile times.
The Honda RVF750R RC45 was a fully faired racing motorcycle created for homologation purposes for the Superbike World Championship by Honda Racing Corporation. The RVF750R was the successor to the VFR750R RC30. Like its predecessor, the RVF750R featured a DOHC liquid-cooled V4 4-stroke engine with gear driven cams and a single-sided swingarm, but unlike the RC30 it utilized electronic fuel injection, in a setup very similar to the production 1992 NR750. The US spec engine had a 749.2cc capacity and was rated at 101 horsepower; the European version was rated at 118 horsepower. A simple rewire modification to the PGM-FI box increased power in the US engine up to the 118 hp. It was manufactured from 1994 until 1995 and sold in limited numbers, followed by the VTR1000R SP-1 RC51 in 2000. Unlike the VFR750R RC30 and VFR750F from which the engine was originally derived the gear drive for the cams was moved from the centre of the engine in between the cylinders to the one side allowing a slightly narrower engine.

The Honda XRE 300 is a single-cylinder dual-sport motorcycle designed and manufactured by Honda in Brazil. It was launched in August 2009 to simultaneously replace the Japanese firm's two South American on/off-road motorcycles: the XR250 Tornado and the NX-4 Falcon. Unlike these motorcycles' 250 cc and 400 cc engines, the fuel-injected 300 cc engine in the XRE300 meets Brazil's new PROMOT 3 emissions rules. It has an anti-lock brake (ABS) option.
The Honda CB400 Super Four is a CB series 399 cc (24.3 cu in) standard motorcycle produced by Honda at the Kumamoto plant from 1992 to the present. The CB400 embodies the typical Universal Japanese Motorcycle produced through the 1970s, updated with modern technology. To this end, the bike has a naked retro design, paired with a smooth inline-four engine. Originally a Japan-only bike, it was later also available in SE Asia, and from 2008 in Australia.
Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine. In a manifold-injected engine, the fuel is injected into the intake manifold, where it begins forming a combustible air-fuel mixture with the air. As soon as the intake valve opens, the piston starts sucking in the still forming mixture. Usually, this mixture is relatively homogeneous, and, at least in production engines for passenger cars, approximately stoichiometric; this means that there is an even distribution of fuel and air across the combustion chamber, and enough, but not more air present than what is required for the fuel's complete combustion. The injection timing and measuring of the fuel amount can be controlled either mechanically, or electronically. Since the 1970s and 1980s, manifold injection has been replacing carburettors in passenger cars. However, since the late 1990s, car manufacturers have started using petrol direct injection, which caused a decline in manifold injection installation in newly produced cars.
