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.

I don’t plan on becoming a full on grease monkey, but I want to have a basic understanding of how everything in my car actually makes it go. At a minimum, this knowledge will allow me to have a clue about what the mechanic is talking about the next time I take my car in. Plus it seems to me that a man ought to be able to grasp the fundamentals of the technology he uses every day. When it comes to this website, I know about how coding and SEO works; it’s time for me to examine the more concrete things in my world, like what’s under the hood of my car.

This type of system is used by a number of suppliers, most commonly in Europe, but hasn't yet come to the market in many areas of the world. Laboe says the amount of increase in fuel economy demonstrated is significant. This technology is coming to meet upcoming regulatory obligations, and Chrysler is interested in this approach because it benefits fuel economy using available energy, and, most importantly, can be incorporated into existing powertrain architectures.

If the box is metal, add a pigtail—a 6-inch length of the same type of ground wire—to the ground wire connection, then connect the loose end of the pigtail to the ground screw on the box. Join the white (neutral) wires together, then join the black (hot) wires together. If there are red (hot) wires, join them together. Confirm that all wires are secure by gently tugging on each wire.

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".

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.

Copper has always been the first choice because it is such a good conductor and is very flexible. In the 1960 to 1970’s, aluminum wire became popular due to the rising cost of copper. Insulation was usually rubber although rubber tended to corrode due to exposure to moisture and air. PVC compounds are now used most commonly as wire insulation. Insulation is made in different colors to identify wiring circuits in a system.

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.

In the 16th century, inventors created a form of internal combustion engine using gunpowder as the fuel to power the movement of the pistons. Actually, it wasn’t the gunpowder that moved them. The way this early internal combustion engine worked was you’d stuff a piston all the way to the top of a cylinder and then ignite gunpowder beneath the piston. A vacuum would form after the explosion and suck the piston down the cylinder. Because this engine relied on the changes in air pressure to move the piston, they called it the atmospheric engine. It wasn’t very efficient. By the 17th century, steam engines were showing a lot of promise, so the internal combustion engine was abandoned.
