Automakers are improving fuel economy by exploiting a new controls approach that uses the waste heat from vehicle engines. Currently, up to 65% of the heat energy produced in internal combustion engines, whether gasoline or diesel, is wasted. Typically, the powertrain or engine dissipates the heat by convection, where it is carried to the cooling circuit or lost out of the tailpipe in exhaust gases.

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.

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.

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.

Inside the grooves piston rings are put in. The piston rings are the part that actually touch the walls of the cylinder. They are made from iron and come in two varieties: compression rings and oil rings. The compression rings are the top rings and they press outward on the walls of the cylinder to provide a strong seal for the combustion chamber. The oil ring is the bottom ring on a piston and it prevents oil from the crankcase from seeping into the combustion chamber. It also wipes excess oil down the cylinder walls and back into the crankcase.

Low-temperature combustion processes are of significant interest due to very high thermal efficiencies with significant reductions in many criteria pollutants. As mentioned above, LTC has been a challenge due to the state of technology: unlike conventional spark-ignition and compression-ignition combustion modes, most LTC modes are kinetically controlled and hence much more sensitive to environmental conditions and ever-changing speed/load demands. Recent advances in enabling technologies such as fuel injection systems, turbomachinery, valve actuation, sensors, and onboard computers have led to new real-time control opportunities which are enabling the potential of LTC engines with production-viable hardware.

A Belgian fellow by the name of Jean Joseph Etienne Lenoir patented an engine that injected natural gas into a cylinder, which was subsequently ignited by a permanent flame near the cylinder. It worked similarly to the gunpowder atmospheric engine, but not too efficiently.
