Identifying and tracing energy flows through many different engines.

Step 2: IN's: Air In

Step 3: In's: Air Preheat

This car was manufactured in Canada and has a lot of preheat mechanisms. For example, this foil air-intake hose draws air from next to the exhaust manifold (one of the hottest regions in the engine, even on startup).

Step 4: Preheat Control

Step 5: IN's: Fuel In

Step 9: (Starter Motor)

The starter motor uses energy from the battery to turn the engine over at first, and get the whole thing going.

Step 10: OUT's: Work Out

Aside from being transmitted through the transmission to the wheels, rotating shaft energy is used to power the alternator, coolant pump, fan, and power steering pump.

Step 12: OUT's: Heat Transfer

This sure brings memories back,I cant believe I actualy owned and drove a car that had "standar" steering and "standard" brakes! lol. I think it was a 1973 Dodge Dart. Oh,initialy I thought that car didnt have any widshield washer mechanism,till I accidentaly stepped on a weird rubber bulb thing near the brake pedal...water landed on the it ended up being a rubber foot pump that you push on to "squirt" water onto the windshield.You had to push or stomp on it hard as it was just a rubber bulb nothing more lol.

The Power Brake Booster shown here is what defines "power brakes", on all cars made after 1964. This device uses engine vacuum (generated by the intake cycle of each cylinder in the engine) to assist the driver in the application of the brakes. Attatched to it is the master cylinder, and on top of that is the reservoir. The lines going to the device on the lower right from the master cylinder go to the proportioning valve, which simpoutaneously meters braking force between front and rear wheels, and divides the braking system into two parts, so that half of the braking system can still operate normally should the other half fail. The wiring harness attached to the PV goes to the brake warning indicator.

Actually the definition of this is incorrect. This tube recovers crankcase vapors to be burned along with combustion. Like the EGR valve, this is an emissions-control device that helps to not only contain and consume oil vapors from the cranckase, but to positively ventilate the crankcase to reduce buildup of acrid oil vapors that can trap moisture in the crankcase. This is the main part of the PCV circuit shown, the one-way PCV valve is within the "box" that the hose is affixed to, forcing vapors into the engine's intake.

Prometheus (author)2006-05-21

The purpose of the shown Exhaust-Gas Recirculation valve is to divert a portion of the exhaust gas to be burned again. This not only reduces emissions, but reduces fuel-vapor buildup in the exhaust, one cause for backfires

Prometheus (author)2006-05-21

What is shown here is the valve that switches from taking in air from over the exhaust manifold, to simply from under the hood. This is shown in the position it is in when the engine is already hot. The hose on the left with the wire-clamp is the engine's coolant intake; the upper radiator hose. Inside of the fitting this attaches to is the thermostat that blocks coolant flow until the engine is warm enough (usually 180-190°F, depending on season)

Prometheus (author)2006-05-21

Actually most cars will be found with this design, since the exhaust manifold heats up fastest and first on the engine. Air is drawn in from over the exhaust manifold to increase intake air temperatures to recapture heat for a quicker warmup, and to help regulate the fuel/air mixture by bringing the carbeurator up to operating temperature with the engine

very nice work! a very good exemple how the net can be a powerful learning instrument. good photos, clear explanations and interesting stuff.
