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

"We first needed to understand how much heat was available from the powertrain during various drive cycles and cold start conditions," he says. By simulating thermal components that control the powertrain heat, such as the electronic thermostat, cooling fans, grill shutters, and water valve, they determined the best way to distribute the available energy.

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.

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.

Most states have a 100 amp minimum requirement. Homes running under that service could consider an upgrade to bring them to between 100 and 200 amps, which could run upwards of $2,000. Homeowners should evaluate their power demands first. “A homeowner can have an electrician test the system with an amp meter while all the big loads are on,” says Holt. “If the draw is over 75-80 percent of the service size, you might consider an upgrade. Otherwise you should be fine.”

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 works in conjunction with the crankshaft via a timing belt to make sure intake and outtake valves open and close at just the right time for optimal engine performance. The camshaft uses egg-shaped lobes that extend across it to control the timing of the opening and closing of the valves.

The cable sheathing (outer jacket) should extend 1/2 to 1 inch beyond the clamp, and the cable wires should extend about 6 inches into the box. If necessary, trim the wires as needed and strip 3/4 inch of insulation from the each of each wire, using wire strippers. Secure the cables by tightening the screws on the clamps, being careful not to overtighten and damage the cables.

Internal combustion engine efficiency has historically been limited more by the state of technology than innovation. As an example, the potential of technologies such as gasoline direct injection were known and attempted in production more than 50 years ago, but direct injection has only become widely available in production within the last decade and now makes up approximately 38 percent of new light-duty vehicle sales. Another example is low-temperature combustion modes such as homogeneous charge compression ignition combustion—in which fuel and air are injected during the intake stroke and then compressed until the entire mixture reacts spontaneously—which were demonstrated in a laboratory more than 30 years ago but are still many years away from market introduction.
By Manon Marianne. Engine Wiring. Published at Wednesday, January 24th 2018, 02:13:22 AM. Gasoline compression ignition combustion is an advanced combustion mode that has received considerable attention in recent years. While GCI combustion is not a new concept, it has evolved over the past several decades as technologies improve. Earlier GCI research was focused primarily on homogeneous charge compression ignition combustion, but in recent years, we have seen increasing interest in a continuous range of GCI combustion modes spanning fully homogeneous HCCI to partial fuel stratification modes to full stratification modes which are diesel-like in execution. These technologies have also led to a strong interest in reactivity controlled compression ignition combustion (RCCI), which makes use of the differences in reactivity of two fuels to manage the combustion process for maximum efficiency with lowest possible emissions.
