ABSTRACT
Engines for motor-cars all run at high speed—not less than 1000 revolutions per minute and until quite petrol has been their only fuel. The more usual name of this fuel among motorists is benzol or benzole. To start the car, a switch is employed to connect the accumulators up in such a way as to drive the dynamo as a motor, and this drives the engine for a few seconds until the explosions begin. The device is simple, reliable, and effective. If the motor-car owes its existence to the petrol-engine, it owes its lightness, speed, strength, and reliability to the new varieties of steel which have been introduced. The modern motor-car is in all cases a comfortable conveyance, and in the more expensive types it embodies a greater degree of luxury than any other medium of locomotion, except perhaps the Atlantic liner. The motor-van or dray is an essential part of military equipment.
