Components for the EIS (1) Inlet manifold pressure sensor (2) Transformer (3) Detonation sensor (4) EIS control module (5) Speed/timing sensor (6) Detonation sensorEIS Control Module
Control module (4) provides the signals for the ignition transformers.Transformers
There is a transformer (2) underneath the valve cover for each cylinder. The transformers deliver high voltage to the spark plugs.Sensors
The sensors provide signals to the control module. The control module uses the signals in order to provide the signals to the transformers at the appropriate time.Inlet Manifold Pressure Sensor
The control module uses the signal from inlet manifold pressure sensor (1) in order to determine the engine load.Detonation Sensors
Detonation sensors (3) and (6) produce a voltage signal that is proportional to the level of detonation. The control module uses the signals from the detonation sensors in order to determine the level of detonation. To eliminate detonation, the control module will retard the ignition timing.Speed/Timing Sensor
Speed/timing sensor (5) provides information to the control module about the position of the crankshaft and the engine rpm. The control module uses the information in order to determine the ignition timing.Distribution Panel

Remote control panelThis panel is configured for CSA. (8) Electronic Control Module (ECM)ECM (8) is located inside an optional remote control panel. The location of the remote control panel varies depending on the customer's requirements. The type of panel that is used depends on the engine's options.Sensors and Actuators

Components for the air/fuel ratio control (9) Inlet manifold temperature sensor (10) Oxygen sensor (11) Oxygen buffer (12) Throttle actuator (13) Fuel actuatorInlet Manifold Temperature Sensor
Inlet manifold temperature sensor (9) provides a signal to the ECM that indicates the temperature of the air/fuel mixture in the inlet manifold. The ECM uses the information in order to control the air/fuel ratio.Oxygen Sensor and Oxygen Buffer
Oxygen sensor (10) and oxygen buffer (11) develop a signal that is proportional to the percent of oxygen in the exhaust manifold. The ECM uses the signal for adjusting the air/fuel ratio in order to achieve the level of emissions that is desired.Throttle Actuator
Throttle actuator (12) provides precise control of the speed of the engine. Linkage connects the throttle actuator to the throttle plate.Fuel Actuator
Fuel actuator (13) provides precise control of the flow of fuel. The fuel actuator provides a position feedback signal to the ECM.Engine Speed Sensor
