I just didn’t have any interest in tooling around under the hood to figure out how my car works. Except for replacing my air filters or changing the oil every now and then, if I ever had a problem with my car, I’d just take it into the mechanic and when he came out to explain what was wrong, I nodded politely and pretended like I knew what he was talking about.

Contrast that to an external combustion engine, where fuel is burned outside the engine and the energy created from that burning is what powers it. Steam engines are the best example of this. Coal is burned outside of the engine, which heats water to produce steam, which then powers the engine.

One of the main trends in the further industrialization of electrical installation work is the use of large-scale electrical engineering facilities, for example, the rooms of electric-drive control stations and of urban transformer substations. Such facilities are delivered by industry with the electrical equipment completely installed and adjusted. In this case, electrical installation work is reduced to the installation of such facilities and the connection of the facilities to external power networks.

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.

The group found that using the waste heat with optimal controls consistently delivered higher oil temperatures and significantly reduced warm-up times. This translated to fuel economy improvements of almost 4% compared to conventional thermal management strategies. The largest efficiency gains occur while heating oil from a cold start, and approximately half of the improvement comes from the powertrain and transmission sides.

The team ran simulations to maximize drivetrain efficiency and minimize fuel consumption under various driving conditions, and tested their model-based approach by delivering control commands to actuators that modulated powertrain heat on a test vehicle. They monitored engine coolant temperature, engine oil temperature, transmission oil temperature, and vehicle fuel consumption, and ultimately found no additional coolant pump power was necessary for rapid warm-up and control of the drivetrain oils.

Opening the grill shutters or running the electric air fan consumes power. Controlling actuators in concert is a new way of addressing thermal management. While more complex, it enables the system to arrive at a steady temperature quicker and under all operating conditions, which extends the life of each thermal-control actuator, Laboe says.

When fuel ignites in the combustion chamber, the force pushes the piston downward, which in turn moves the crankshaft (see below). The piston attaches to the crankshaft via a connecting rod, aka the con rod. It connects to the connecting rod via a piston pin, and the connecting rod connects to the crankshaft via a connecting rod bearing.
