V10 Engine
A V10 engine is a ten- cylinder piston engine where two banks of five cylinders are arranged in a V configuration around a common crankshaft. V10 engines are much less common than V8 and V12 engines. Several V10 diesel engines have been produced since 1965, and V10 petrol engines for road cars were first produced in 1991 with the release of the Dodge Viper. Design The V10 configuration does not have perfect engine balance, since an unbalanced rocking couple is caused by each cylinder bank functioning as a straight-five engine. Therefore, balance shafts are sometimes used to reduce the vibrations in a V10 engine. Diesel engines One of the first known V10 engines was used in the 1936 ''Busch-Sulzer ICRR 9201'' prototype locomotive, of which three examples were produced in the United States. The 1965–1984 Leopard 1 armored tank was powered by the ''MTU MB 838 CaM 500'' V10 diesel engine. Daimler-Benz produced three V10 diesel engine models (OM403, OM423 and OM443) ...

Dry Sump
A dry sump system is a method to manage the lubricating motor oil in Four-stroke engine, four-stroke and large Two-stroke engine, two-stroke Reciprocating engine, reciprocating internal combustion engines. The dry sump system uses two or more oil pump (internal combustion engine), oil pumps and a separate oil reservoir, as opposed to a conventional wet sump system, which uses only the main sump (American English, U.S.: oil pan) below the engine and a single pump. A dry sump engine requires a Relief valve, pressure relief valve to regulate negative pressure inside the engine so that internal seals are not inverted. Dry sump lubrication is common on larger diesel engines such as those used in ships, as well as gasoline engines used in Auto racing, racing cars, Aerobatics, aerobatic aircraft, high-performance personal watercraft, and Motorcycle, motorcycles. Dry sumps may be chosen for these applications due to increased reliability, oil capacity, reduction of oil starvation under ...

Gasoline Engines By Model
Gasoline (North American English) or petrol (English in the Commonwealth of Nations, Commonwealth English) is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. When formulated as a fuel for petrol engine, engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries. The ability of a particular gasoline blend to resist premature ignition (which causes Engine knocking, knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Tetraethyl lead was once widely used to increase the octane rating but is not used in modern automotive gasoline due to the Lead poisoning#Gasoline, health hazard. Aviation, off-road motor vehicles, and racing car engines still use leaded ...

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 * ...

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 ...

Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length, along with bore diameter, determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion ...

Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds ( rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. In steam locomotives The term bore also applies to the cylinder of a steam locomotive or steam engine. Bore pitch Bore pitch is the distance between the centerline of a cylinder bore to the centerline of the next cylinder bore adjacent to it in an internal combustion engine. It's also referred to as the "mean cylinder width", "bore spacing", "bore center distance" and "cylinder spacing". The bore pitch is always larger than the inside diameter of the cylinder (the bore and piston diameter) sinc ...

Redline
The redline is 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. Redlining is riding or driving an automotive vehicle above the redline. The actual term ''redline'' comes from the red bars that are displayed on tachometers in cars starting at the rpm that denotes the redline for the specific engine. Straying into this area usually does not mean instant engine failure, but may increase the chances of damaging the engine. Variation of redline The acceleration, or rate of change in piston velocity, is the limiting factor. The piston acceleration is directly proportional to the magnitude of the G-forces experienced by the piston-connecting rod assembly. As long as the ...

Torque
In physics and mechanics, torque is the rotational analogue of linear force. It is also referred to as the moment of force (also abbreviated to moment). The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . Just as a linear force is a push or a pull applied to a body, a torque can be thought of as a twist applied to an object with respect to a chosen point; for example, driving a screw uses torque to force it into an object, which is applied by the screwdriver rotating around its axis to the drives on the head. Historical terminology The term ''torque'' (from Latin , 'to twist') is said to have been suggested by James Thomson and appeared in print in April, 1884. Usage is attested the same year by Silvanus P. Thompson in the first edition of ''Dynamo-Electric Machinery''. Thompson describes his usage of the term as follows: Today, torque is referred to using d ...

Power (physics)
Power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. Power is a Scalar (physics), scalar quantity. Specifying power in particular systems may require attention to other quantities; for example, the power involved in moving a ground vehicle is the product of the aerodynamic drag plus traction (engineering), traction force on the wheels, and the velocity of the vehicle. The output power of a Engine, motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a electrical circuit, circuit is the product of the electric current, current flowing through the element and of the voltage across the element. Definition Power is the Rate (mathematics), rate with respect to time at which work is done or, more generally, the rate of change of total mechanical energy. It is ...
