There are typically two stages of fuel injectors: low impedance and high impedance.
Low impedance injectors have a resistance of around 2-4 ohms and are commonly used in high-performance engines.
High impedance injectors have a resistance of around 12-16 ohms and are commonly used in standard engines.
The number of stages refers to the different resistance levels of the injectors.

The diesel engine combustion process involves the ignition of fuel injected into the combustion chamber by compressed air.
Diesel fuel is injected into the combustion chamber at high pressure
The air in the combustion chamber is compressed by the piston, leading to high temperatures
The high temperature air ignites the fuel, leading to combustion and the generation of power
The combustion process in diesel engines is more
A two-stroke engine completes a power cycle in two strokes of the piston, while a four-stroke engine completes it in four strokes.
Two-stroke engines have a simpler design with fewer moving parts compared to four-stroke engines.
Two-stroke engines typically produce more power for their size but are less fuel-efficient and emit more pollution.
Four-stroke engines are more common in cars, motorcycles, and larger machinery d...
A hydraulic component is a device that utilizes fluid power to perform mechanical tasks.
Hydraulic components use liquid to transmit power.
Common examples include hydraulic cylinders, pumps, motors, valves, and hoses.
They are often used in heavy machinery, construction equipment, and industrial applications.
Realy is a type of relay used in electrical systems to control high power devices with low power signals.
Relays are switches that open and close circuits electromechanically
Realy is a type of relay specifically designed for high power applications
Working principle involves an electromagnet that moves an armature to open or close the circuit
Commonly used in industrial automation, automotive, and HVAC systems
Least count is the smallest change in the measured quantity that can be detected by the measuring instrument.
Least count is determined by the smallest division on the scale of the measuring instrument.
It is important for accurate measurements and precision in engineering.
For example, a ruler with millimeter divisions has a least count of 1 mm.
A vernier caliper with 0.1 mm divisions has a least count of 0.1 mm.
