MPI Epsilon 0.8

(814cc)

M5EF1

Bi-FUEL Epsilon 0.8 + LPG

- Epsilon engine is already used for Santro and i10

 Instead of 4 cylinder, 3 cylinder is applied for HA

 BI fuel engine is for India market only

 Bi fuel use two fuel like as LPG and gasoline

At engine idle condition after warm

up, normally oil pressure reaches 147kpa(1.5kg/ ㎠ )

Oil pressure switch is screwed near

engine oil filter When the oil

pressure goes down less than 0.5kg/

㎠ , oil pressure warning lamp turns

CKP Sensor

Hall IC type CKP sensor is used

ECM No 15 is used for sensor

signal.

Unlike other general target

wheel which is composed with

60 teeth including 2 missing

teeth, it has 30 teeth with 2

missing

Reference Point Missing Tooth

CMP sensor is also used from Hall

IC

It distinguishes the cylinder No

by comparing with CKP sensor

It is located near ignition coil

Front or Up Stream Oxygen Sensor

Rear or Down Stream

Oxygen Sensor

Zirconia type oxygen sensor is used

The Zirconia oxygen sensor generates a small voltage depending on the exhaust gas condition

The normal voltage range is 0.2 ~ 0.8 volts 0.2 volts indicates a lean

mixture and a voltage of 0.8v indicates a richer mixture
