Coolant is circulated through the engine by the:
camshaft |
|
radiator |
|
water pump |
|
water jacket |
The water pump is driven by a belt connected to the crankshaft and ensures that coolant moves through the engine and radiator.
What is the large casing that contains the cylinders and many of the internal components of the engine?
transmission |
|
engine block |
|
chassis |
|
manifold |
The engine (or cylinder) block is the large casing that contains the cylinders and many of the internal components of the engine.
Waste gases from combustion are removed from the combustion chamber by the:
exhaust valve |
|
camshaft |
|
head gasket |
|
piston |
The combustion chamber is located in the cylinder head and contains the combustion of the air-fuel mixture. This mixture is delivered by an intake valve and the waste gases from combustion are removed from the combustion chamber by the exhaust valve.
Opposed cylinder designs feature two rows of cylinders that are placed at what angle to each other?
90° |
|
270° |
|
180° |
|
45° |
Opposed cylinder designs place cylinders flat in two rows 180° opposite each other with a single crankshaft running between them.
Which of the following is a common firing order for four-cylinder engines?
1-3-4-2 |
|
3-1-2-4 |
|
1-2-3-4 |
|
4-3-2-1 |
The stroke cycle of an engine is governed by the crankshaft which serves to regulate the firing order of the cylinders. All cylinders are not on the same stroke at the same time and correct firing order is important to balance engine operation and minimize vibrations. A common firing order for four-cylinder engines is 1-3-4-2 which indicates that cylinders 1 and 3 fire (power stroke)together and cylinders 4 and 2 fire together.
