Investigation – Investigating Distributorless Ignition Systems Distributorless ignition systems (DIS) are used to ensure the air and fuel mixture in an engine is ignited at exactly the right time for efficient combustion to occur. They comprise mechanical and electrical components that, together, provide appropriate timing of the spark at each spark plug. Use the information in the related presentation to identify the components and voltage waveforms of DIS. Distributorless Ignition Systems a) Identify the components of this distributorless ignition system. A - ECU B - Crankshaft position sensor C - Ignition control module D - Coil pack E - Spark plug wires F - Spark plugs b) Draw a diagram to show the relationship between the primary voltage waveform and the secondary voltage waveform for one ignition coil. Ensure the diagram shows the waveforms for 2 spark plugs. A typical early DIS system will comprise which of these components? Select all the correct answers. Ignition control...
Investigation - Definition of Electric Vehicles An electric vehicle (EV) uses an electric traction motor for propulsion. A ‘pure’ EV does not have an engine. The Nissan Leaf is an example of a pure EV. It uses a front-mounted electric traction motor to drive the road wheels, powered by a high voltage (HV) battery pack located under the floor and seats. The vehicle produces zero tailpipe emissions at its point of operation. Use the Nissan Leaf Information Sheet to find out more about the Nissan Leaf, and then answer the questions that follow. Nissan Leaf Information Sheet contract Performance and Range Performance: The Nissan Leaf can reach a top speed of over 93 mph (150 km/h). It can accelerate from 0 to 60 mph (0 to 97 km/h) in approximately 9.9 seconds. Range: The range obtained from a single charge will depend on vehicle load, traffic conditions, driving style, weather, and accessory use. The average range figure from Nissan is 73 miles (118 km)....
