The system was a speed/density system, using engine speed and intake manifold air density to calculate the amount of fuel to be injected. In 1974, Bosch introduced the K-Jetronic system, which used a continuous flow of fuel from the injectors (rather than the pulsed flow of the D-Jetronic system). K-Jetronic was a mechanical injection system ...
The D-400 series engine or the Iron Horse engine was a light-duty two-stroke engine used for powering lawnmowers produced from the 1950s to the late 1970s. D-400 engines were single-cylinder engines designed and manufactured by the Outboard Marine Corporation (OMC; Johnson and Evinrude) for Lawn-Boy [2] and Masport.
Programmed Fuel Injection, or PGMFI/PGM-FI, is the name given by Honda to a proprietary digital electronic multi-point injection system for internal combustion engines.It has been available since the early 1980s.
Some small engines use a pull-rope mechanism called "recoil starting", as the rope rewinds itself after it has been pulled out to start the engine. This method is commonly used in pushed lawn mowers and other settings where only a small amount of torque is needed to turn an engine over.
The carburetor supplies a mixture of fuel and air into the engine, with the proportions kept fairly constant and their total volume throttled to control the engine power. Apart from sharing the diesel's use of compression ignition, their construction has more in common with a small two-stroke motorcycle or lawnmower engine.
The only significant difference between the two was the inclusion of electronic fuel injection on the 1FZ-FE, whereas the 1FZ-F used a carburetor. [ 2 ] The 1FZ-F produced 188 hp (140 kW) at 4400 rpm and 268 lb⋅ft (363 N⋅m) at 2800 rpm; its fuel injected counterpart produced 212 hp (158 kW) at 4600 rpm and 275 lb⋅ft (373 N⋅m) at 3200 rpm.
The basic operation of a feedback carburetor: The carburetor would take in a signal from the oxygen sensor and would determine if the mixture was correct; If the mixture needed to be adjusted, a solenoid or stepper motor would move to adjust the AFR; Most included electric chokes for cold starting
The 2V (two carburetor venturi) small port cylinder heads were used on 2-barrel engines while the 4V (four venturi) large port cylinder heads were used on the 4-barrel engines. [4] The ports and valves on 2V heads were significantly larger than Windsor engines [9] and had excellent flow - actually slightly better than 4V heads at lower valve ...
