Diesel Fuel Injector Nozzle Tips DSLA148P042 / F019123042 for JMC Foton ISUZU 4JB1, 4JB1T, and JX493Q1 engines — OEM direct fit, 4-hole, 148° spray cone.
The Diesel Fuel Injector Nozzle with part numbers DSLA148P042 and F019123042 is a direct-fit replacement for ISUZU 4JB1, 4JB1T, and domestic JX493Q1 / 493ZQ-3FE diesel engines, widely used in JMC (Jiangling), Foton, and Isuzu light trucks. Installed in the injector body, this DSLA-type nozzle atomizes diesel fuel into a fine mist for combustion, directly affecting engine power, fuel economy, and emissions.
Pressurized fuel from the injection pump enters the nozzle body and lifts the needle valve against spring pressure. Fuel exits through 4 precision-drilled holes at a 148° spray cone angle, creating a fine mist that mixes with intake air for efficient combustion. Worn or clogged nozzles cause poor atomization, leading to rough idle, power loss, and increased smoke.
