Toyota GZ Engine
The Toyota GZ engine family consists of a single model, the 1GZ-FE. This engine is used as the powerplant for the second generation Century limousine from 1997 to 2017. 1GZ-FE The 1GZ-FE is a 48-valve DOHC V12 engine with variable valve timing ( VVT-i). Bore is 81 mm and stroke is 80.8 mm, with a compression ratio of 10.5:1. The official power output advertised in Japan per the gentlemen's agreement is at 5,200 rpm, though it was advertised as in export markets. Peak torque of is at 4,000 rpm with over available from as little as 1200 rpm. The Electronic fuel-injection system is controlled by two ECUs, one for each bank of six cylinders. The engine is capable of running on either bank should a malfunction occur. In 2010 the standard engine was revised in order to meet tough fuel economy and emissions standards, reducing power slightly and peak torque to although this torque figure had been advertised in export markets since at least 2004. ;Ap ...

Compression Ratio
The compression ratio is the ratio between the maximum and minimum volume during the compression stage of the power cycle in a piston or Wankel engine. A fundamental specification for such engines, it can be measured in two different ways. The simpler way is the static compression ratio: in a reciprocating engine, this is the ratio of the volume of the cylinder when the piston is at the bottom of its stroke to that volume when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gases entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to be reached wit ...

Toyota Engines
This is a list of piston engines developed, independently or with other car companies, by Toyota Motor Corporation. Engine codes Toyota has produced a wide variety of automobile engines, including three-cylinder, four-cylinder, V6 and V8 engines. The company follows a naming system for their engines: # The first numeric characters specify the engine block's model (usually differed by displacement) # The next one or two letters specify the engine family # The suffix (separated by a dash) specifies the features of the engine: Other manufacturers may modify the engine after it has left the Toyota factory but the engine still keeps the original Toyota designation. For example, Lotus added a supercharger to the 2ZZ-GE in some versions of the Lotus Elise and Exige, but the engine is still labelled 2ZZ-GE, not 2ZZ-GZE. Examples: * 3S-GTE ** 3S – Third model in the S engine family ** G – Performance cylinder head DOHC ** T – Turbocharged ** E – Multi-point fuel injection * ...

Acoustic Control Induction System
''Acoustic Control Induction System'', or ACIS, is an implementation of a variable-length intake manifold system designed by Toyota. Simply put, the ACIS system uses a single intake air control valve located in the intake to vary the length of the intake tract in order to optimize power and torque, as well as provide better fuel efficiency and reduce intake "roar". The engine control unit (ECU) controls the position of one or more air control valves based on input signals from throttle angle and engine RPM. The vacuum switching valve (VSV) which controls the vacuum supply to the actuator is normally closed and passes vacuum to the actuator when it is energized by the ECU. By energizing the VSV vacuum is passed to the actuator, closing the air control valve. This effectively lengthens the intake manifold run. By de-energizing the VSV, vacuum to the actuator is blocked and trapped vacuum is bled off of the actuator diaphragm. Toyota ACIS is an On/Off system. The valve (or valves in ...

Emission Standard
Emission standards are the legal requirements governing air pollutants released into the atmosphere. Emission standards set quantitative limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes. They are generally designed to achieve air quality standards and to protect human life. Different regions and countries have different standards for vehicle emissions. Regulated sources Many emissions standards focus on regulating pollutants released by automobiles (motor cars) and other powered vehicles. Others regulate emissions from industry, power plants, small equipment such as lawn mowers and diesel generators, and other sources of air pollution. The first automobile emissions standards were enacted in 1963 in the United States, mainly as a response to Los Angeles' smog problems. Three years later Japan enacted their first emissions rules, followed between 1970 and 1972 by Canada, Australia, and several ...

Fuel Economy In Automobiles
The fuel economy of an automobile relates to the distance traveled by a vehicle and the amount of fuel consumed. Consumption can be expressed in terms of the volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since the importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses ( wind resistance, tire drag, and others) encountered while propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning. Various strategies can be employed to reduce losses at each of the conversions between the chemical energy in the fuel and the kinetic energy of the vehicle. Driver behavior can affect fuel economy; maneuvers s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Fuel-injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while carburetion relies on suction created b ...

Gentlemen's Agreement
A gentlemen's agreement, or gentleman's agreement, is an informal and legally non-binding wikt:agreement, agreement between two or more parties. It is typically Oral contract, oral, but it may be written or simply understood as part of an unspoken agreement by convention or through mutually beneficial etiquette. The essence of a gentlemen's agreement is that it relies upon the honor of the parties for its fulfillment, rather than being in any way enforceable. It is distinct from a contract, legal agreement or contract. A more formal (but still non-binding) form of the gentlemen's agreement is the memorandum of understanding. History The phrase appears in the British parliamentary records in 1821 and in the Massachusetts public records in 1835. The ''Oxford English Dictionary'' cites P. G. Wodehouse's 1929 story collection ''Mr Mulliner Speaking'' as the first appearance of the term. Industry A gentleman's agreement, defined in the early 20th century as "an agreement between gent ...

VVT-i
VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing petrol engine technology manufactured by Toyota Group and used by brands Groupe PSA (Peugeot and Citroen), Toyota, Lexus, Scion, Daihatsu, Subaru, Aston Martin, Pontiac and Lotus Cars. It was introduced in 1995 with the '' 2JZ-GE'' engine found in the JZS155 Toyota Crown and Crown Majesta. The VVT-i system replaces the Toyota VVT system introduced in 1991 with the five-valve per cylinder '' 4A-GE'' "Silver Top" engine found in the AE101 Corolla Levin and Sprinter Trueno. The previous VVT system was a 2-stage hydraulically controlled cam phasing system. VVT-i varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt or chain) and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft position. Adjustments in the overlap time between the exhaust valve closing and intake valve opening result in impr ...
