It is critical in any wiring project that you match the gauge of the wire with the amperage rating of the circuit. Failing to do so can lead to a fire. A wire's gauge is the physical size of the wire, but the scale is opposite of the wire's circumference. This means that a 2-gauge wire is actually larger than a 14-gauge wire. The size determines how much current can pass through, so the larger wires will be used for your heavier loads.

The NEC is used in conjunction with local, country, and State codes that strictly control electrical wiring. The codes are concerned with proper size of wire and with insulation. Factors that are considered are the expected load, the frequency of modifications, and the nature of the environment where the wire is used. Homes have small loads, infrequent modifications and a very non-corrosive environment. Commercial establishments are usually in the middle. The load demands are sometimes higher, and modifications are not infrequent. The factory or industrial site has a very high demand. Modifications are frequent, and the environment is often highly unstable.

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.

Many low-temperature combustion modes such as GCI and RCCI operate on the edge of stability—in other words, at conditions under which very small variations in engine boundary conditions (such as intake temperature) may result in unintended excursions that result in undesirable emissions, reduced efficiency, and the potential to destroy the engine or emissions control system. One can imagine the challenge of these types of combustion modes under ever-changing conditions of a real-world drive cycle where a single unintended excursion could be catastrophic. Meeting that challenge requires a control system which is predictive for avoidance rather than reactive after the occurrence of a potentially damaging event.

The crankshaft is what converts the up and down motion of the pistons into a rotational motion that allows the car to move. The crankshaft typically fits lengthwise in the engine block near the bottom. It extends from one end of the engine block to the other. At the front of the end of the engine, the crankshaft connects to rubber belts which connect to the camshaft and delivers power to other parts of the car; at the back end of the engine, the camshaft connects to the drive train, which transfers power to the wheels. At each end of the crankshaft, you’ll find oil seals, or “O-rings,” which prevent oil from leaking out of the engine.
By Faustine Arnaud. Engine Wiring. Published at Friday, September 15th 2017, 15:48:57 PM. 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.

So without further ado, we’ll begin our first class of Gearhead 101 by explaining the ins and outs of the heart of a car: the internal combustion engine. An internal combustion engine is called an “internal combustion engine” because fuel and air combust inside the engine to create the energy to move the pistons, which in turn move the car "we’ll show you how that happens in detail below".

I’ll show you how the four-stroke engine works here in a bit, but before I do, I thought it would be helpful to go through the various parts of an engine so you’ll have an idea of what’s doing what in the four-stroke process. There is terminology throughout these explanations that relies on other terms in the list, so don’t worry if you get confused at first. Read through the whole thing to get an overall grasp, and then read it again so you have a basic understanding of each piece as it’s being talked about.
