Blackburn Approximately 730 references to books, papers, and reports are listed on ignition of combustible gaseous mixtures and ignition apparatus. The ignition of gases includes ignition by electric sparks and arcs and by hot surfaces. The references on ignition apparatus are for the most part on ignition systems and components for internal-combustion engines, with spark plugs listed separately from other components. 1. Introduction This publication supersedes National Bureau of Standards Circular 580. It covers the initiation of combustion in explosive gaseous mix- tures by means other than compression ignition, as well as electric equipment for spark-ignition engines. Part 2.1 lists books in which ignition or ignition equipment is either the main topic or is given fairly extensive treatment. The references to other publications are presented under three main heads. The first concerns ignition of combustible mixtures of gases and vapors, and is subdivided into two parts, according to whether ignition is effected by an electric spark or arc or by a heated surface. Part 2.2. a includes references to work on measuring spark energy. Part 2.2. b covers both fundamental investigations of ignition by heated surfaces and ignition by hot spots in internal-combustion engines. Although ignition is an essential stage in the combustion process, papers dealing primarily with the kinetics of combustion, flame propa- gation, and detonation, or with the flammability limits of composition, temperature, and pressure of gases, have not been included in this bibliography unless they were found to contribute also to an under- standing of ignition phenomena. Part 2.3 lists references on spark-ignition systems for internal- combustion engines, and their components. It includes work on test- ing and test equipment. Because there are so many references to spark plugs, these are listed separately as part 2.3.b. Part 2.4 contains miscellaneous references on ignition that do not fall within the category of part 2.2. Included are a number of papers and reports concerning explosion hazards and ignition of fuels used in rocket propulsion. Within each topical subdivision the references are given in chrono- logical order, and within each chronological subdivision, alphabeti- cally by author, followed by anonymous references. The journal abbreviations used are those employed in Chemical Abstracts, except that the abbreviation NACA is used for the Na- tional Advisory Committee for Aeronautics and SAE J. for the Journal of the Society of Automotive Engineers. An unpublished paper presented before a technical or professional society is designated by the abbreviation M. P. for Meeting Paper. Volume numbers are in boldface, and the date of issue is given in cases where page numbers do not run consecutively through a given volume. 1 . In general, the reports and papers listed are available only in ! i 1 wanes, and none can be supplied by the Bureau. The Federal Specification for Spark Plugs, W-S-506(2) (listed in part 2.3.b), may be obtained for 10 cents from the Business Service Qnter, Fed- eral Supply Service, General Services Administration Regie aial Office, \ Washington D.C. 20407. The sources of translation of several articles in foreign languages are given. Some of these are available from the Office of Technical Services Department of Commerce, (OTS), U.S. , Washington D.C. 20230. That agency can usually furnish informa- tion as to the availability of translations of other foreign-language articles.

It has become a fashion for the people especially living in urban areas to ride such vehicles. Now the companies even want to launch such vehicles that attract the younger generation. This can be achieved by technology known as DTSi. Due to DTSi (digital twin spark ignition) system it is possible to combine strong performance and fuel efficiency. The improved engine efficiency modes have also resulted in lowered fuel consumption. The efficiency of these small engines were enhanced with increased power output just by increasing the number of fuel igniting element i.e. Spark Plug. Spark ignition is one of the most vital systems of an engine. Any variation in the spark timing and number of sparks per minute affects the engine performance severely. Thus a good design and control of the system parameters becomes most essential for optimum performance of an engine. Due to Digital Twin Spark Ignition system it is possible to combine strong performance and higher fuel efficiency. DTSi offers many advantages over conventional mechanical spark ignition system.

  • HEI System - Description and Diagnosis Chart
    HEI System - Description and Diagnosis Chart No. T -36 February, 1978 The High Energy Ignition System (HEI) In 1974 General Motors began equipping passenger cars and light trucks with an electronic ignition system called High Energy Ignition (HEI). The HEI is different in many ways from the previously standard breaker-point ignition system . ^ Higher available secondary voltage of 35,000 volts. ^ The secondary spark plug wires are larger diameter with silicone rubber insulation. This type of wire minimizes cross firing or arching between wires. The silicone insulation is softer than rubber insulation, so wires should be routed to avoid chafing on the engine or accessories. The insulation should never be punctured with sharp tools. The boots fit tightly on the spark plug insulators and are thus sometimes difficult to remove from the spark plugs. Tools are available from several tool companies to make removal easier. ^ Distributor cap and rotor are made of special material to handle the higher secondary voltage. ^ An internal condenser is for reducing radio interference and is not a normal replacement item. ^ There is no resistance wire or ballast resistor between the ignition switch and the coil. The system operates on full battery voltage. Zoom Sized for Print ^ The ignition coil is mounted in the distributor cap on most engines. Figure 1. ^ Some 4-cylinder and L-6-cylinder ignition coils are mounted outside of the distributor but are different in appearance from previously standard ignition coils. Zoom Sized for Print ^ Breaker points are no longer used, so point maintenance and replacement is eliminated. Instead of breaker points, a magnetic pickup and an electronic module are used.

  • Airplane Flying Handbook (FAA-H-8083-3B) Chapter 2
    Chapter 2 Ground Operations Introduction All pilots must ensure that they place a strong emphasis on ground operations as this is where safe flight begins and ends. At no time should a pilot hastily consider ground operations without proper and effective thoroughness. This phase of flight provides the first opportunity for a pilot to safely assess the various factors of flight operations including the regulatory requirements, an evaluation of the airplane’s condition, and the pilot’s readiness for their pilot in command (PIC) responsibilities. 2-1 Flying an airplane presents many new responsibilities that are not required for other forms of transportation. Focus is often overly placed on the flying portion itself with less emphasis placed on ground operations; it must be stressed that a pilot should allow themselves adequate time to properly prepare for flight and maintain effective situational awareness at all times until the airplane is safely and securely returned to its tie-down or hangar. This chapter covers the essential elements for the regulatory basis of flight including an airplane’s airworthiness requirements, important inspection items when conducting a Figure 2-2.

  • Unit – I - Rockets System – Sae1402
    SCHOOL OF MECHANICAL ENGINEERING DEPARTMENT OF AERONAUTICAL ENGINEERING UNIT – I - ROCKETS SYSTEM – SAE1402 1 I. Ignition System An ignition system is a system for igniting a fuel-air mixture. Ignition systems are well known in the field of internal combustion engines such as those used in petrol (gasoline) engines used to power the majority of motor vehicles, but they are also used in many other applications such as in oil-fired and gasfired boilers, rocket engines, etc. Diesel engines rely on air compression for ignition, but usually also have glow plugs that preheat the combustion chamber to allow starting of the engine in cold weather. Other engines may use a flame, or a heated tube, for ignition. Types 1. Magneto systems 2. Switchable systems 3. Battery and coil-operated ignition 4. Modern ignition systems 5. Mechanically timed ignition 6. Electronic ignition 7. Digital electronic ignitions Magneto systems Magneto ignition coil. For more details on this topic, see Ignition magneto. The simplest form of spark ignition is that using a magneto. The engine spins a magnet inside a coil, or, in the earlier designs, a coil inside a fixed magnet, and also operates a contact breaker, interrupting the current and causing the voltage to be increased sufficiently to jump a small gap. The spark plugs are connected directly from the magneto output. Early magnetos had one coil, with the contact breaker (sparking plug) inside the combustion chamber. In about 1902, Bosch introduced a double-coil magneto, with a fixed sparking plug, and the contact breaker outside the cylinder. Magnetos are not used in modern cars, but because they generate their own electricity they are often found on piston-engined aircraft engines and small engines such as those found in mopeds, lawnmowers, snowblowers, chainsaws, etc.
