  2. Engine tuning - Wikipedia

    en.wikipedia.org/wiki/Engine_tuning

    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 ...

  3. Wasted spark system - Wikipedia

    en.wikipedia.org/wiki/Wasted_spark_system

    A wasted spark system is a type of ignition system used in some four-stroke cycle internal combustion engines. In a wasted spark system, the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke. The extra spark during the exhaust stroke has no effect and is thus ...

  4. Ignition timing - Wikipedia

    en.wikipedia.org/wiki/Ignition_timing

    Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.

  5. Performance tuning - Wikipedia

    en.wikipedia.org/wiki/Performance_tuning

    See the main article at Performance engineering. Performance engineering is the discipline encompassing roles, skills, activities, practices, tools, and deliverables used to meet the non-functional requirements of a designed system, such as increase business revenue, reduction of system failure, delayed projects, and avoidance of unnecessary usage of resources or work.

  6. Trionic 8 - Wikipedia

    en.wikipedia.org/wiki/Trionic_8

    The Trionic 8 is an advanced engine management system in the Trionic series, created by Saab Automobile.It is used in both Saab 9-3 and Opel Vectra vehicles, and is available with 150, 175 and 210 horsepower (160 kW) engines.

  7. Maximum brake torque - Wikipedia

    en.wikipedia.org/wiki/Maximum_brake_torque

    Maximum brake torque (MBT) is the use of optimal ignition timing to take advantage of an internal combustion engine's maximum power and efficiency.. There is always an optimal spark timing for all operating conditions of an engine.

  8. Alfa Romeo Twin Spark engine - Wikipedia

    en.wikipedia.org/wiki/Alfa_Romeo_Twin_Spark_engine

    The Alfa Romeo Modular Inlet Manifold is a variable intake system fitted to the later CF2 1.8 and 2.0 litre Twin Spark engines. [citation needed] It operates by switching between two separate air intake runners of different lengths (one pair for each cylinder) to either shorten or lengthen the path from the end of the intake runner (within the plenum) to the inlet valves.

  9. Car tuning - Wikipedia

    en.wikipedia.org/wiki/Car_tuning

    Car tuning is the modification of a car to optimise it for a different set of performance requirements from those it was originally designed to meet. Most commonly this is higher engine performance and dynamic handling characteristics but cars may also be altered to provide better fuel economy , or smoother response.
