Engine Management System Quiz

What was used before the days of programmable engine management?

• Turbochargers and Superchargers

• Carburetors and Distributors

• Throttle Position Sensors and Manifold Pressure Sensors

• Fuel Injectors and Ignition Coils

What are the critical input sensors for the engine management system?

• Thermop Fans, Shift Flights, Tachos, Variable Cam Control

• Air Temperature, Coolant Temperature, Throttle Position, Manifold Pressure, Engine Speed

• Oil Pressure, Exhaust Gas Temperatures, Air Fuel Ratios

• Fuel Pressure, Exhaust Gas Temperatures, Air Fuel Ratios

What is a lookup table in the engine management system used for?

• To adjust the engine speed and load

• To adjust the air to fuel ratio

• To monitor fuel pressure and oil pressure

• To control the fuel injectors and the ignition system

What is the purpose of base Maps in the engine management system?

• To control the fuel injectors and the ignition system

• To monitor fuel pressure and oil pressure

• To provide preconfigured lookup tables for different engines and racing types

• To adjust the air to fuel ratio

What are the additional outputs that can be controlled by the engine management system?

• Fuel Pressure, Exhaust Gas Temperatures, Air Fuel Ratios

• Oil Pressure, Exhaust Gas Temperatures, Air Fuel Ratios

• Thermop Fans, Shift Flights, Tachos, Variable Cam Control

• Air Temperature, Coolant Temperature, Throttle Position, Manifold Pressure, Engine Speed

What is the main function of the engine management system?

• To add a metered amount of air and fuel into the engine

• To control the fuel injectors and the ignition system

• To monitor fuel pressure and oil pressure

• To distribute the spark to the right spark plug

What are the inputs that come into the engine management system from the engine?

• Oil Pressure, Exhaust Gas Temperatures, Air Fuel Ratios

• Air Temperature, Coolant Temperature, Throttle Position, Manifold Pressure, Engine Speed

• Thermop Fans, Shift Flights, Tachos, Variable Cam Control

What is the purpose of the ECU in the engine management system?

• To add a metered amount of air and fuel into the engine

• To distribute the spark to the right spark plug

• To control the fuel injectors and the ignition system

• To act as a computer with inputs and outputs for engine control

What do the inputs from the engine allow the engine management system to know?

• How to adjust the air to fuel ratio

• How efficient the engine is at a particular point in time

• How much fuel and ignition timing the tuner wanted the engine to have

• How fast the engine is turning, the demand or load on the engine, and the temperature of the coolant and air

What is the purpose of the lookup tables in the engine management system?

• To adjust the engine speed and load

• To provide preconfigured lookup tables for different engines and racing types

• To adjust the air to fuel ratio

• To monitor fuel pressure and oil pressure
