MSN Encarta - Internal-Combustion Engine The fourth stroke, as in the Otto-cycle engine, is an exhaust stroke. Four principal types of internal-combustion engines are in general use: the Otto-cycle engine, the diesel engine, the rotary engine, and the gas turbine. The Otto-cycle engine, named after its inventor, the German technician Nikolaus August Otto, is the familiar gasoline engine used in automobiles and airplanes; the diesel engine, named after the French-born German engineer Rudolf Christian Karl Diesel, operates on a different principle and usually uses oil as a fuel. encarta.msn.com /encyclopedia_761553622/Internal-Combustion_Engine.html   (1498 words)

Best Car 1970-1979 In the stratified-charge engine there was a tiny auxiliary chamber atop the main combustion chamber. In Japan Soichiro Honda of Honda Motor Co. introduced the CVCC stratified-charge engine, which not only met the U.S. emission standards without a catalytic converter but also met the stringent Japanese emission standards. The 1.5-L engine had a bore of 74 mm (2.91 in), stroke of 86.6 m (3.41 in), and a compression ratio of 8.1:1. www.autocluster.com /id53.htm   (207 words)

Transportation Allowing a modest twenty million such engines built per year throughout the world, the annual waste due to the monopolization of the stratified charge engine technology would be $24 billion, or $408 billion over the seventeen-year life of the patent. It was used in diesel engines in 1911, patented for gas engines in England in 1922, patented by the Soviet Union in 1958, and patented by others in the early 1960s. Although its engineers had long ago solved the emissions problem, the industry had chosen to ignore their solution and did not own the patents to this critical technology. www.ied.info /books/www/transportation.html   (6105 words)

The Honda Civic and Civic CVCC Website A very effective stratification of the charge is thus attained, through which the flame front propogates with certainty and at a controlled rate. In fact, the lower half of the engine is common with the sister 1500 (non-CVCC) unit available in the same body shell. Engineer Kawamoto, one of Honda's young prodigies, concedes that electronics may do the work but adds wryly that an electronic fuel injection not all electronic; imagine a microscopic injection nozzle that shoots and controls fuel into a 6 cc chamber! www.luk-korbmacher.de /Autos/randt.htm   (3675 words)

q&a Your VLB engine looks to be a sort of "DISC" (Direct Injection Stratified Charge) engine, as developed by HONDA in the late 1980s. The high NOX emissions (at higher engine speeds and loads) were also due to propagation difficulties resulting in incomplete decomposition of the heavier molecules (a situation known to give rise to NOX production). At low fuel inputs (low load) the fuel dispersion was too rare and the flame front was unable to propagate throughout all of the charge, leaving unburned hydrocarbons. www.vlbengine.com /q&a.html   (218 words)

stratified charge engine - yourDictionary.com - American Heritage Dictionary stratified charge engine - yourDictionary.com - American Heritage Dictionary An internal-combustion engine with a divided ignition cylinder that uses the ignition of rich fuel in a small chamber near the spark plug to improve the combustion of a very lean mixture throughout the rest of the cylinder. www.yourdictionary.com /ahd/s/s0797300.html   (58 words)

Direct Gasoline Injection The development of electronically-controlled stratified charge GDI engines was an extremely costly undertaking, collectively costing the auto industry hundreds of millions of dollars. Mitsubishi's development of its Gasoline Direct Injection engine is an extension of long term Japanese research into fuel and induction systems that can create a precisely layered air/fuel mixture (or stratified charge). Improvements in stratified charge technology was required to move to the next step in fuel delivery -- direct fuel injection. www3.telus.net /Volvo_Books/engine6.html   (588 words)

Honda Civic - Reviews, Information, Pictures, Pricing, and Links. An interesting engine developments used in 1980 to 1983 models was the CVCC system, where a small auxilary inlet valve allowed a rich fuel/air mixture into the cylinder near the spark plug, while the main charge was lean. This engine was a rare example of commercial development of a Stratified charge engine. A hybrid version is also available that uses a combination gas-electric hybrid engine for propulsion, which reduces exhaust emissions and greatly extends fuel mileage. www.isvee10.com /Honda-Civic.html   (681 words)

Auto Racing Articles: Direct-Injection Engine The direct-injection stratified charge engine attempts to incorporate many of the high efficiency features of a diesel into a spark-ignited gasoline engine. To slow the engine down, the flow of air into it is restricted, increasing the amount of energy wasted pumping air. To avoid throttling losses, the DISC engine must be able to run "lean" (less fuel per volume of air than a conventional engine). speedarticles.com /auto_racing_article-39.html   (244 words)

Internal Combustion Engine Technologies The advanced fuel injectors atomize the fuel into a fine mist in two stages; the combustion chamber "swirls" the air and fuel; and a computerized electronic management system controls the engine operation and turbocharger, fine-tuning the entire process for fuel efficiency and emission control. The "new" diesel engines directly inject fuel into the combustion chamber rather than having part of the combustion occur in a prechamber (indirect injection). Unlike diesel engines sold in this country during the 1970s and 80s, modern passenger car diesels are quieter, smoother, more responsive and almost entirely free of diesel odor. www.fueleconomy.gov /feg/icetech.shtml   (138 words)

Active Skim View of: 7 Discussion As discussed in Section 4.2, the diverse conditions to be undergone by the engine and control systems during 50,000 miles of customer use are far more strenuous than those undergone during certification. 7.3.3 Wankel Engines As shown in Table 3-7, the Wankel engine with thermal reactor on a compact car has met the 1975 standards with NOx levels of about 1 g/mile for 50,000 miles, but with a fuel penalty of about 30 percent compared with a 1973 equivalent piston engine. Although American manufacturers and others evidently will be able to produce catalyst-equipped vehicles capable of certification for the 1975 model year, and even possibly capable of 1976 certif~cation, compliance with the certification procedure, of itself, may not constitute indication of satisfactory performance of catalyst-equipped vehicles in actual customer use. www.nap.edu /nap-cgi/skimit.cgi?isbn=NI000564&chap=113-127   (764 words)

Halfbakery: Boiled Gasoline Engine Such designs generate a fraction of the horsepower of a gasoline engine, because the less-dense charge results in lower mass of charge per fired cylinder...and this is with considerable *cooling* of the charge from the temperature drop that occurs when gas is released from pressurized storage conditions. The gasoline that continually passes through the fuel lines on your vehicle will not stay in one place long enough to become heated to its boiling point; especially as it is already under pressure to the tune of 30-60 psi, depending on the system. Thus, the engine management system would 'think' that the air-fuel mixture is richer than the ideal stoichiometric ratio, and hence, proceed to 'lean back' the mixture by reducing the pulse width modulated duty cycle of the fuel injectors. www.halfbakery.com /idea/Boiled_20Gasoline_20Engine   (5562 words)

GREEN CAR JOURNAL ONLINE The engine is restarted when the accelerator is applied again, a gear is selected with the clutch disengaged on manual transmission vehicles, the brake pedal is released during deceleration, or the battery module’s state-of-charge drops below a threshold level. The engine will be shut down if the battery module state-of-charge is sufficient, although the engine may idle for a short time before stopping if it’s not clear that a stop is imminent. If the battery module state-of-charge is low, some of the engine’s output drives the IMA motor/generator operating in generator mode for recharging. www.greencar.com /index.cfm?content=features24   (1503 words)
