Description

A fuel enhancement kit for each vehicle model that includes a large-capacity injector and fuel pump.

■Features

The injector uses the current generation top feed type manufactured by BOSCH. We conduct a complete injection test and set the ones with similar performance to one car model.
Ineffective injection time has been shortened by improving the performance of the injector. (1350μsec ⇒ 900μsec when power supply voltage is 14V and fuel pressure is 300kPa)
Two O-rings and a spacer (backup ring) are used at the injector’s fuel delivery line connection to improve sealing performance.
A conversion connector is included with the injector to connect it to the genuine harness.
The fuel pump continues to be used from the previous fuel upgrade kit. When installing to GRB/GVB, it is necessary to replace the connector and partially modify the fuel case (same as before)

Fuel line connection with improved sealing performance

■Performance

Relationship between fuel pressure and injector injection amount (calculated value based on nominal injection amount)

Fuel pressure (kPa)	250	300	350	400
Injection amount (ml/min)	595	650	700	750

Relationship between fuel pressure and pump discharge amount (discharge amount is not guaranteed)

Fuel pressure (kPa)		300	350	400	450	500
Discharge amount (L/h)	12(V)	210	195	180	165	150
Discharge amount (L/h)	14(V)	260	245	230	215	200

Relationship between drive voltage and injector invalid injection time (at 300kPa)

Voltage (V)	8	Ten	12	14	160
Ineffective injection time (μ sec)	2290	1560	1150	900	730

■Notes

While conventional injectors are 2jet types, this product is a conical spray (1 spray) type. Since the injection characteristics and invalid injection time are different from conventional products, fuel setting data cannot be used.
