A'PEXi

Last updated

A'PEXi is a Japanese aftermarket automotive parts company that was created in 1992. The company's focus is on parts designed to enhance engine performance. These include turbos, intercoolers, exhaust systems, [1] and engine control units [2] as well as many other smaller components. A'PEXi is a JDM brand which has been relatively successful in the United States. Like other Japanese aftermarket automotive parts companies, parts are available for many Japanese cars, but availability for cars from other countries is usually relatively sparse. A'PEXi's diesel particulate filter systems are standard in Tokyo on metropolitan public diesel buses. [3] They also were the first to create the technology that allows the security system of the car to be accessed from a cellular phone, with videos and pictures. They plan to carry this technology over into home security and other applications. [3]

Japan Island country in East Asia

Japan is an island country in East Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asian continent and stretches from the Sea of Okhotsk in the north to the East China Sea and the Philippine Sea in the south.

Intercooler specific type of mechanical device used to cool liquid or gas

An intercooler is a mechanical device used to cool a gas after compression process. Compression process increases the internal energy of the gas which in turn raises its temperature and reduces the density. In other words intercooler is a device used in compression process, typically a heat exchanger that removes waste heat in a gas compressor. They are used in many applications, including air compressors, air conditioners, refrigeration, and gas turbines, and automotive engines. Here they are widely known as an air-to-air or air-to-liquid cooler for forced induction internal combustion engines to improve their volumetric efficiency, which they do by increasing intake air density through nearly constant pressure cooling. First introduced in 1977 on the Porsche 911, although these were the first cars to use intercoolers they were not the first cars to use turbochargers; in fact they weren’t even the first 911’s to use turbochargers.

Exhaust system

An exhaust system is usually piping used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system design, the exhaust gas may flow through one or more of:

Products

A'PEXi supplies the following products (among many others):

Muffler noise silencer

A muffler is a device for reducing the noise emitted by the exhaust of an internal combustion engine. This noise deadening device is especially one forming part of the exhaust system of an automotive vehicle.

Intake An opening or structure through which a fluid is admitted to a space or machine

An intake is an opening or structure through which a fluid is admitted to a space or machine as a consequence of a pressure differential between the outside and the inside. The pressure difference may be generated on the inside by a mechanism, or on the outside by ram pressure or hydrostatic pressure. Flow rate through the intake depends on pressure difference, fluid properties, and intake geometry. An intake can be an outlet at the same time – the intake for a hydro-electric generator turbine may be an outlet for a dam, where the turbine is inside relative to the dam, and the dam is inside relative to the river valley below.

An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a "mover".

Turbocharger forced induction device for internal combustion engines

A turbocharger, colloquially known as a turbo, is a turbine-driven forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra compressed air into the combustion chamber. This improvement over a naturally aspirated engine's power output is due to the fact that the compressor can force more air—and proportionately more fuel—into the combustion chamber than atmospheric pressure alone.

Engine tuning the adjustment, modification, or design of internal combustion engines to yield more performance

Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability. These goals may be mutually exclusive; an engine may be de-tuned with respect to output power in exchange for better economy or longer engine life due to lessened stress on engine components.

Car tuning practice of modifying automobiles

Car tuning is the modification of the performance. Most vehicles stay stock for an average driver's expectations and conditions, although tuning has become a way to personalize the characteristics of a vehicle to the owner's preference. Cars may be altered to provide better fuel economy, produce more power, or provide better handling and driving.

Nissan RB engine

The RB engine is a 2.0–3.0 L straight-6 four-stroke gasoline from Nissan, produced from 1985–2004 and will be continuing production in 2019, after a 15 year hiatus.

Ford Power Stroke engine

Power Stroke is a name used by a family of diesel engines for trucks produced by Ford Motor Company since 1994. Along with its use in the Ford F-Series, applications include the Ford E-Series, Ford Excursion, and Ford LCF commercial truck; the name was also used for a diesel engine used in South American production of the Ford Ranger.

Lean-burn refers to the burning of fuel with an excess of air in an internal combustion engine. In lean-burn engines the air:fuel ratio may be as lean as 65:1. The air / fuel ratio needed to stoichiometrically combust fuel, by contrast, is 14.64:1. The excess of air in a lean-burn engine emits far less hydrocarbons. High air–fuel ratios can also be used to reduce losses caused by other engine power management systems such as throttling losses.

Crankcase

A crankcase is the housing for the crankshaft in a reciprocating internal combustion engine. The enclosure forms the largest cavity in the engine and is located below the cylinder(s), which in a multicylinder engine is usually integrated into one or several cylinder blocks. Crankcases have often been discrete parts, but more often they are integral with the cylinder bank(s), forming an engine block. Nevertheless, the area around the crankshaft is still usually called the crankcase. Crankcases and other basic engine structural components are typically made of cast iron or cast aluminium via sand casting. Today the foundry processes are usually highly automated, with a few skilled workers to manage the casting of thousands of parts.

Toyota S engine

The Toyota S Series engines are a family of straight-4 engines with displacement from 1.8 L to 2.2 L produced by Toyota Motor Corporation from January 1980 to August 2007. The series has cast iron engine blocks and alloy cylinder heads.

Variable-geometry turbocharger Type of turbocharging technology

Variable-geometry turbochargers (VGTs),, are a family of turbochargers, usually designed to allow the effective aspect ratio (A:R) of the turbo to be altered as conditions change. This is done because optimum aspect ratio at low engine speeds is very different from that at high engine speeds. If the aspect ratio is too large, the turbo will fail to create boost at low speeds; if the aspect ratio is too small, the turbo will choke the engine at high speeds, leading to high exhaust manifold pressures, high pumping losses, and ultimately lower power output. By altering the geometry of the turbine housing as the engine accelerates, the turbo's aspect ratio can be maintained at its optimum. Because of this, VGTs have a minimal amount of lag, have a low boost threshold, and are very efficient at higher engine speeds. VGTs do not require a wastegate.

Twincharger refers to a compound forced induction system used on some piston-type internal combustion engines. It is a combination of an exhaust-driven turbocharger and a mechanically-driven supercharger, each mitigating the weaknesses of the other. A mechanically-driven supercharger offers exceptional response and low-rpm performance as it does not rely on pressurization of the exhaust manifold. A turbocharger sized to move a large volume of air tends to respond slowly to throttle input while a smaller, faster-responding turbo may fail to deliver suffcient volume through an engines upper RPM range. The unacceptable lag time endemic to a large turbocharger is effectively neutralized when combined with a supercharger which tends to generate substantial boost pressure much faster in response to throttle input. The end result being a zero-lag powerband with high torque at lower engine speeds and increased power at the upper end. Twincharging is therefore desirable for small-displacement motors, especially those with a large operating rpm, since they can take advantage of an artificially broad torque band over a large speed range.

In an internal combustion engine, a crankcase ventilation system (CVS) is a one way, pressure-sensitive passage which allows the natural build up of gases to escape from the crankcase in a controlled manner.

Twin-turbo or biturbo refers to a turbocharged engine in which two turbochargers compress the intake charge. The most common layout features two identical turbochargers in parallel; other twin-turbo layouts include sequential and staged turbocharging, the latter of which is used in diesel auto racing applications.
