Injectors

Injectors

Fuel injectors are vital to the efficient and clean operation of any diesel engine. They precisely deliver fuel into the combustion chamber under high pressure — and even a slight variation in injection timing, pressure, or spray pattern can impact performance, emissions, and fuel economy.

At AMS Parts, we supply genuine and OEM injectors that meet exact manufacturer specifications, ensuring optimal combustion and reliable engine operation across all industrial, generator, and marine applications.

When Should Injectors Be Replaced?

Injectors wear over time due to fuel contamination, carbon build-up, or simply prolonged use. Common indicators include:

• Hard starting or misfiring
• Poor fuel economy
• Excessive smoke or unburnt fuel
• Engine knock or rough idle
• Loss of power or sluggish performance
• Scheduled replacement at OEM-recommended intervals
