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 ...
Break-in or breaking in, also known as run-in or running in, is the procedure of conditioning a new piece of equipment by giving it an initial period of running, usually under light load, but sometimes under heavy load or normal load. It is generally a process of moving parts wearing against each other to produce the last small bit of size and ...
Overview. Inertial supercharging effect is the result of incoming fuel/air charge developing momentum greater than intake stroke would generate alone. It is achieved by the careful design of the shape of the piston head, the valves and cam profile/ valve timing which creates a vacuum that pulls more exhaust gases (and some of the intake gasses ...
Engines Became More Tempting in 2020. The rare rat found nesting in an engine isn't so rare anymore. According to reports from publications such as The New York Times and the Detroit Free Press ...
The term "engine braking" refers to the braking effect that occurs in gasoline engines when the accelerator pedal is released. This causes fuel injection to cease and the throttle valve to close almost completely, greatly restricting forced airflow from, for example, a turbocharger. The restriction causes a strong manifold vacuum which the ...
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 ...
Automotive research firm J.D. Power’s highly watched initial quality study is out — and it appears EVs are giving consumers big headaches.
Step 3: Attach the battery charger to your vehicle's battery terminals. Always start by attaching the charger's red clamp to the battery's positive terminal and then attaching the black clamp to ...
