The direct acting mechanical governor used with some small diesel engines, controls fuel flow to the engine by __________.

🔍 Key Concepts

• Direct-acting mechanical governor vs. hydraulic or servomotor-type governors • How flyweights in a governor transmit motion to the fuel rack or fuel control • What components are typical in a small diesel engine fuel control system (no external oil pressure or servomotor)

💭 Think About

• Which choices mention devices that clearly require hydraulic or servo assistance, and which describe a more simple, purely mechanical linkage? • In a small diesel engine with a direct mechanical governor, how does the motion of the spinning flyweights actually get to the fuel control—through oil pressure, through a valve, or by direct linkage? • Does a small diesel fuel system normally use a butterfly valve in the fuel line, or is fuel quantity controlled in another way?

✅ Before You Answer

• Identify which options involve a pilot valve or servomotor piston (these are usually not purely mechanical direct-acting types). • Consider how a simple mechanical governor in textbooks is usually drawn: flyweights, a sleeve, springs, and a linkage connected directly to the fuel rack or control. • Eliminate any option that relies on a device you would expect in a more complex, hydraulic, or pneumatic control system rather than a direct-acting mechanical one.
