Components of an automotive car that are impacted due to change in the engine

Components of an automotive car that are impacted due to change in the engine

(OP)
Hello all - I am analyzing two vehicle Bills of Material to see the impact due to changing the engine (say from a 1.6L Turbo diesel to a 1.4 L Gasoline engine). What are the major parts of the vehicle that would be impacted? For example - the fuel tank, fuel filter, catalytic converters and possibly starter motors are obvious parts that are impacted due to engine type. Appreciate if someone can share their insights. Thanks, Subramanian V

RE: Components of an automotive car that are impacted due to change in the engine

Instrument cluster, if it has a tachometer and the maximum revs are different (which is highly likely if one is comparing a diesel to a gasoline engine). Instrument cluster again, given that the diesel engine will need a glow plug warning lamp and possibly a DPF warning lamp, and the gasoline engine won't need that. The gasoline engine will need an evaporative control system (charcoal canister) plus all the valves and hoses to make it work; the diesel engine won't. The transmission, if the engines operate in different RPM ranges, which is usually the case between diesel and gasoline. The transmission again and the clutch, if the diesel engine has a torque rating beyond what the transmission for the gasoline engine will handle and it thus needs a "beefier" transmission and clutch. The diesel engine with modern emission control systems likely requires a "diesel exhaust fluid" storage tank, heating system (for below-freezing temperature conditions), dosing pump, and a means of filling that tank. The diesel engine will require additional high-capacity electrical systems for operating its glow plugs.

Engine mounts. Subframe, if the engine mounts are in different places. Sound insulation around the engine compartment (diesels often have more of it). Front suspension springs and dampers, if the engine is of significantly different weight.

From a manufacturing perspective, to get the car to work optimally:

This is not a complete list. I don't have time for that but this will maybe help get the wheels turning.
Transmission gearing, frame rigidity, suspension, fuel pump, controls systems(ecu), cooling system (radiator sizing), power brakes/steering systems have different options

I guess he already passed in his homework.

It's the sort of question I would hope is asked by a competitor.
