Automakers can improve fuel economy by selecting optimal coolant-circuit architectures, heat exchangers, and flow-control devices. The goal of this work was to warm up the drivetrain oils rapidly and run at a slightly higher temperature without additional hydraulic power. Kevin Laboe, who leads the Powertrain Thermal Management Team at Chrysler's Advanced Powertrain Group, Detroit, MI, and who led the simulation and testing teams, says the challenge was to distribute the heat in the most effective way.

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.

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.

New appliances come with their own electrical challenges, which is why many people choose to pay for the installation. Yet, if you're a true DIY-er, you can install a dishwasher without problems. The dishwasher comes with two hook-up challenges: the wiring and the water and drain lines. That's why it's a good idea to choose a location near your sink. It will save you time and money. Why oh why do you have to buy a dryer cord separately? It's one of the great mysteries of home improvement, but it's a fact of life. Next time you need to install that new dryer, you'll be prepared after this tutorial.

The engine is undergoing a significant evolution of its own, as new fuel economy and emissions standards in the light-duty and heavy-duty sectors push the development of new technologies on an unprecedented scale toward the theoretical limits of engine operation. Coupled with continuing research into fundamental engine processes, the introduction of affordable high-performance computing, and the adoption of advanced manufacturing techniques throughout industry, those new technologies are leading to potentially disruptive opportunities for the introduction of engines with extraordinarily high efficiencies. How these new engines perform and how they will be integrated into new vehicle architectures will be the story of personal mobility for this half of the 21st century.

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.
By Thibault Margaux. Engine Wiring. Published at Tuesday, January 23rd 2018, 16:16:00 PM. The internal combustion engine has seen a remarkable evolution over the past century. Before 1970 the evolution of engine design was driven by a quest for performance and an increase in octane in the fuel supply. Since then, however, the imperative was the need to meet new emissions and fuel economy regulations.

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.

Over the past several years, road transportation has seen some significant advances in what are considered alternative technologies. Energy storage, electric drive systems, and fuel cell technology all seem to be poised to find a significant place in the automotive marketplace. But it would be a mistake to believe that such technologies will completely sweep aside what has come before. Instead, the internal combustion engine will continue to be integral to the transportation of people and goods for the foreseeable future.

Our cities, towns, states and the entire country are crisis-crossed withpower lines that ³carry´ the electricity. As large generators spin, they produce electricitywith a voltage of about 25,000 volts. A volt is a measurement of electromotive force inelectricity. The electricity first goes to a transformer at the power plant that boosts thevoltage up to 400,000 volts. When electricity travels long distances it is better to have itat higher voltages "more efficiently at high voltages".
