How many injectors does a 4 cylinder engine have?
A car generally has one fuel injector per cylinder. So, if you drive a four-cylinder car, it will most likely have four fuel injectors.
What is the firing order of a 4 cylinder engine?
4-Cylinder Engines:
In the case of 4-cylinder engines, the crankpins are 90 degrees apart. So, manufacturers use 1-3-4-2 or 1-2-4-3 as firing order for 4-cylinder engines.
What is EFI engine system?
Electronic fuel injection replaces the need for a carburetor that mixes air and fuel. It injects fuel directly into an engine's manifold or cylinder using electronic controls. ... While the auto industry has been enjoying the technology for decades, it's not as common in smaller engines.
How does an EFI fuel system work?
An EFI system consists of a fuel pump, fuel injectors, sensors and an Engine Control Unit (ECU). Fuel gets pumped up from the tank via a fuel pump out to a fuel injection rail, then into individual injectors which are inserted directly into the intake manifold. The fuel injectors are controlled by the ECU.
What is the difference between the manifolds used on EFI engine and diesel engine?
EFI injectors inject fuel into the inlet manifold. Either just downstream of the throttle, supplying all the cylinders together, or right at each individual inlet valve, supplying each cylinder separately. Diesel injectors inject fuel straight into the cylinders.
Where are fuel injectors located?
Fuel injectors are located in the intake manifold and spray fuel through a tiny nozzle. The fuel injector uses a special nozzle to spray the fuel as mist, instead of a strong jet stream.
What is the firing order of a 4 cylinder engines Mcq?
Explanation: The firing order of a four cylinder engines is 1-3-4-2.
What is cylinder firing order?
The firing order of an internal combustion engine is the sequence of ignition for the cylinders. ... The firing order heavily influences crankshaft design. In a Diesel engine, the firing order corresponds to the order in which fuel is injected into each cylinder.
Which is cylinder 1 on a 4 cylinder engine?
Originally Answered: Which cylinder is number 1 on a 4 cylinder? Generally, in a four-cylinder, number one cylinder is the one at the front of the engine. Most cars use a transverse mounted engine. The front of the engine is the end with the timing chain/belt, the balancer and the drive belts for engine accessories.
What are the two main types of EFI systems?
Port or multipoint fuel injection. Sequential fuel injection.
What is EFI on a 4 wheeler?
Electronic fuel injection technology is a system that uses computers to directly inject fuel into an engine. The computer system allows the EFI system to monitor outside conditions and adjust the fuel mixture sent to the engine.
How does port injection work?
Port injection sprays fuel into the intake ports, where it mixes with the incoming air. ... When the intake valve opens, the fuel mixture is pulled into the engine cylinder. With direct injection, the injectors are in the cylinder head and spray fuel directly into the combustion chamber, mixing with the air charge.
What is the advantage of EFI engine?
EFI-equipped engines provide higher power and torque than a carbureted version of the same engine. They optimize air/fuel ratios and ignition timing while compensating for other factors to maintain continuous optimum performance.
