Most folks think that in the world of mechanized movement, steam-powered external combustion engines came before the internal combustion variety. The reality is that the internal combustion engine came first. "Yes, the ancient Greeks messed around with steam-powered engines, but nothing practical came from their experiments".

Building on that work, in 1864 two German engineers named Nicolaus August Otto and Eugen Langen founded a company that made engines similar to Lenoir’s model. Otto gave up managing the company and started working on an engine design that he had been toying with since 1861. His design led to what we now know as the four-stroke engine, and the basic design is still used in cars today.

A joint team from Chrysler and the Center for Automotive Research at The Ohio State University recently developed a practical approach to maximizing drivetrain efficiency and reducing fuel consumption and carbon dioxide emissions. Together, engineers in industry and research, along with students, determined how to capture and effectively distribute the useful heat energy to the transmission and engine oils from a controls standpoint, requiring additional hardware such as a transmission heat exchanger and associated plumbing, and new software. Higher temperature oil is less viscous, so less torque is required for operation and the transmission and engine can operate at higher mechanical efficiencies.

Along the crankshaft you’ll find balancing lobes that act as counterweights to balance the crankshaft and prevent engine damage from the wobbling that occurs when the crankshaft spins. Also along the crankshaft you’ll find the main bearings. The main bearings provide a smooth surface between the crankshaft and engine block for the crankshaft to spin.

The crankcase is located beneath the cylinder block. The crankcase protects the crankshaft and connecting rods from outside objects. The area at the bottom of a crankcase is called the oil pan and that’s where your engine’s oil is stored. Inside the oil pan, you’ll find an oil pump that pumps oil through a filter, and then that oil is squirted on to the crankshaft, connecting rod bearings, and cylinder walls to provide lubrication to the movement of the piston stroke. The oil eventually drips back down into the oil pan, only to begin the process again

The push toward higher-efficiency engines will alter exhaust temperatures and chemistry and may create challenges for emission control technologies. For example, new higher-efficiency engines will have lower exhaust temperatures, due to more efficient work extraction at the piston. Lower exhaust temperatures will, in turn, require the development of new emission control technologies, which must not only be effective at low temperatures but also must survive high exhaust temperatures encountered under high load conditions.

It’s where fuel, air, pressure, and electricity come together to create the small explosion that moves the car’s pistons up and down, thus creating the power to move the vehicle. The combustion chamber is made up of the cylinder, piston, and cylinder head. The cylinder acts as the wall of the combustion chamber, the top of the piston acts as the floor of the combustion chamber, and the cylinder head serves as the ceiling of the combustion chamber.
By Olivier Danielle. Engine Wiring. Published at Saturday, August 26th 2017, 23:40:52 PM. The engine block is the foundation of an engine. Most engine blocks are cast from an aluminum alloy, but iron is still used by some manufacturers. The engine block is also referred to as the cylinder block because of the big hole or tubes called cylinders that are cast into the integrated structure. The cylinder is where the engine’s pistons slide up and down. The more cylinders an engine has the more powerful it is. In addition to the cylinders, other ducts and passageways are built into the block that allow for oil and coolant to flow to different parts of the engine.
