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.

"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.

Most engine blocks are cast from an aluminum alloy, but iron is still used by some manufacturers. The engine block is also referred to as the cylinder block because of the big hole or tubes called cylinders that are cast into the integrated structure. The cylinder is where the engine’s pistons slide up and down. The more cylinders an engine has the more powerful it is. In addition to the cylinders, other ducts and passageways are built into the block that allow for oil and coolant to flow to different parts of the engine.

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.

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.

Most folks think that in the world of mechanized movement, steam-powered external combustion engines came before the internal combustion variety. The reality is that the internal combustion engine came first. "Yes, the ancient Greeks messed around with steam-powered engines, but nothing practical came from their experiments".

Game-changing advances in recent years are improvements in engine technologies, sensors, and onboard computing power. This combination of technologies will enable unprecedented control of the combustion process, which in turn will enable real-world implementations of low-temperature combustion and other advanced strategies as well as improved robustness and fuel flexibility. In fact, technological advances are blurring our historical distinction between spark-ignition and compression-ignition engines; we will see new engine concepts that blend the best characteristics of both engine types to push the boundaries of efficiency while meeting stringent emissions regulations worldwide.
