Single-point injection was a relatively low-cost way for automakers to reduce exhaust emissions to comply with tightening regulations while providing better "driveability" (easy starting, smooth running, no engine stuttering) than could be obtained with a carburettor. Many of the carburettor's supporting components—such as the air filter ...
The system uses tubes with poppet valves from a central injector to spray fuel at each intake port rather than the central throttle body [citation needed]. Fuel pressure is similar to a single-point injection system. CPFI (used from 1992 to 1995) is a batch-fire system, while CSFI (from 1996) is a sequential system. [9]
Petrol engines often use simple fuel systems consisting of a float-type carburetor with a fuel tank located above it (so that the fuel is delivered by gravity, avoiding the need for a fuel pump). Sometimes, the fuel tank is located below the carburetor and fuel is delivered using engine vacuum or crankcase pressure pulsations.
These engines gave good performance and had up to 30% less fuel consumption over the carburetor version, primarily under low engine loads. [44] An added benefit of the system was having a separate tank for the engine oil which was automatically added to the fuel mixture, obviating the need for owners to mix their own two-stroke fuel blend.

In the case of a CI engine, the fuel injector quickly injects fuel into the combustion chamber as a spray; the fuel ignites due to the high temperature. Power or working stroke: The pressure of the combustion gases pushes the piston downward, generating more kinetic energy than is required to compress the charge. Complementary to the ...
In a naturally aspirated engine, air for combustion (Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre ...
Compact utility tractors equipped with a belly mower can look similar to riding lawn mowers, but they are typically larger, equipped with diesel engines, and feature a three-point hitch and rollover protection structure; these features are generally absent on riding lawn mowers. The deck of a rotary mower is typically made of steel.
The original engine featured a Mikuni two-barrel carburetor with a secondary vacuum actuator; later versions adopted EFI. Chrysler commonly paired this engine with its A470 3-speed automatic transmission; in Australia, Mitsubishi adapted it to a 5-speed manual transmission and its "ELC" (Electronic Control) 4-speed automatic transmission ...
