GM powertrain engines

shared by Molly Brookshire on 29 Apr 14 - No Cached
  • GM introduced one of the biggest engine programs in its history. Later this spring GM will debut the first of a new family of small Ecotec engines, 11 in all, that will be built around the world in five plants by 2017. The new three- and four-cylinder engines will eventually account for nearly 25 percent of GM’s total engine production and produced at the rate of 10,000 engines a day.
  • GM and Ford are collaborating on a new generation of 9- and 10-speed transmissions. The 10-speed gearboxes will be used in both company’s pickups in about two years. The F-150 and the GM twins, Chevrolet Silverado and GMC Sierra, lag far behind Chrysler’s Ram 1500 Ecodiesel in the fuel economy race.
  • for the time being, both trucks use six-speed transmissions, while the Ram has 8-speeds.

  • GM said it will divide vehicle engineering into two organizations: Global Product Integrity and Global Components and Subsystems.
  • The product integrity organization will include the new global vehicle safety group that GM created in February, led by Jeff Boyer. That unit also will oversee supplier quality and include vehicle, powertrain and electrical-systems engineering; vehicle performance; industrial engineering and validation, GM said.
  • GM said the product integrity organization will use "advanced analysis tools and processes to flag and prevent issues during vehicle development." It also will analyze field reports "to react quickly to safety and product quality issues customers may experience."

Toyota engines fuel efficiency

shared by Molly Brookshire on 14 Jul 14 - No Cached
  • Toyota Motor Corp., after long neglecting the humble internal combustion engine in favor of hybrids, is preparing a sweeping powertrain makeover.
  • The automaker is designing common parts to spread costs across large numbers of engines. This will allow it to economically customize engines for specific vehicles with fuel injection, turbocharging and more.
  • The goal is to cut costs and maximize performance by standardizing the basics: bore, stroke, combustion cycle, valve timing and components such as engine blocks, cylinder heads, cam-shafts and crankshafts. After that is where the hair ornaments come in.

  • The strategy underscores how Toyota is playing catch-up in a fundamental field, as rivals gain on the automaker's top fleet average fuel economy in the United States with big advancements in such fuel-saving technologies as direct injection, turbocharging and stop-start systems. For years, Toyota has focused on its best-selling gasoline-electric hybrid systems. It hasn't abandoned that track.
  • Toyota is seeking fuel economy increases of up to 30 percent and cost cuts on key components of up to 50 percent.
  • "Just like putting something beautiful on top of your hairdo, by using kanzashi through such things as turbocharging or downsizing, you can improve the performance of the engine."Kanzashi add-ons may include direct fuel injection, exhaust gas recirculation systems or stop-start technologies that turn off the engine when the vehicle stops.
  • The EPA's annual report on fuel economy trends, which calculates automakers' fleet average fuel economy based on sales, shows Toyota losing ground to rivals such as Nissan and Mazda. For example, in 2010, Toyota's U.S. fleet average fuel economy was 25.4 mpg. In 2013, it was 25.2 mpg. Meanwhile, Mazda improved from 24.4 mpg in 2010 to 27.5 mpg in 2013, and Nissan rose from 23.3 mpg to 24.6 mpg during the period.
  • "Eventually we think this is where the technology is going, but right now we don't know what the reaction of U.S. customers will be," he said. "So probably right up until the last moment, we will have to be ready with both and watch customer feedback."

  • Japan’s automakers, aiming to take the lead in fuel-efficient powertrains, have joined forces in a new consortium to develop the next generation of fuel-sipping combustion engines.
  • Their goal: A 30 percent improvement in the fuel efficiency of traditional gasoline and diesel engines by 2020.
  • The Japanese government will aid the country’s eight automakers by chipping in half of the project’s 1 billion yen ($9.9 million) budget. The automakers will foot the rest.

  • Research Association of Automotive Internal Combustion Engines. It pools the resources of Toyota Motor Corp., Nissan Motor Co., Honda Motor Co., Mazda Motor Corp., Mitsubishi Motors Corp., Daihatsu Motor Co., Suzuki Motor Corp. and Fuji Heavy Industries Ltd., the maker of Subaru-brand vehicles.
  • The objective is to share costs in an increasingly competitive, investment-heavy field to meet more stringent fuel economy guidelines, organizers
  • The strategy is patterned after a similar approach taken by competitors in Europe, organizers said. There, rivals cooperate with academia and the government on basic technologies, giving European carmakers a head start in cutting costs.
  • While Japanese automakers have developed advanced electric and hybrid drivetrains, the creation of AICE acknowledges that internal combustion engines will remain the workhorse of global fleets for a long time, especially in cost-sensitive emerging markets.
  • Organizers outlined a 10-year time frame for achieving world-leading advancements in combustion engine efficiency.
  • Engineers target thermal efficiency rates for both approaching 50 percent. That compares with today’s best rates of around 39 percent for gasoline engines and 42 percent for diesel engines. Higher thermal efficiency means more energy from internal combustion is captured for higher engine output. Organizers said such a breakthrough could boost the fuel efficiency of gasoline and diesel engines 30 percent by 2020.
  • Diesel engine development will focus on eliminating particulate matter and nitrogen oxide emissions, partly through better particulate filters and exhaust gas recirculation systems. Gasoline engine research will focus on achieving more complete combustion cycles and better ignition while reducing knock.
  • Keiji Ohtsu, managing officer of Honda R&D Co., Honda’s product development arm, will be AICE president.
