Hybrid Technology in Honda Civic IMA

Honda Civic IMA Hybrid

The Civic Integrated Motor Assist (IMA) Hybrid System is based on an electric motor mounted between the engine and the transmission. This motor assists with extra torque which considerably reduces the vehicle’s pollution levels.

The Civic Hybrid Technology recovers and transforms the energy that is lost during deceleration and braking. This technology stores the electric power in order to assist the engine when electric power is required.

It should be noted that the engine uses two ignition coils per cylinder, as well as the variable distribution system VTEC.

The electric motor works at 158V 3-phase AC, and it is used to start the engine and also as a generator that charges the battery. That is to say, the electric motor acts as a starter motor and an alternator.

The 158V battery is formed by 20 modules of 6 cells, each one connected in series. Each cells voltage is 1.32V.
