  • DYNO Testing)
    TyrolSport UG Side Mount Intercooler - The new standard in upgraded Side Mount Intercoolers for 1.8T Golf/Jetta (DYNO Testing) The aftermarket for the 1.8T has been booming, as people come to realize the potential of this stout motor in a relatively light chassis. Up until now, the upgrade path for the stock intercooler has been to replace the stock Sidemount intercooler(SMIC) with a larger unit, or to scrap it altogether and go with a Front Mount unit(FMIC). It has been held as common knowledge that SMICs are inferior to FMICs in all performance applications. Regardless of turbo, horsepower, vehicle use, FMICs have trumped SMICs in popularity. Part of this due to the fact that all the big horsepower cars run FMICs. The other part seems to be that it is inconceivable to many that an SMIC can indeed perform equal to an FMIC. The goal of the TyrolSport UG SMIC was to combine the performance of an FMIC with the cost and easy packaging and installation of an SMIC. We spent the better part of a day today testing three intercoolers. The stock sidemount, The TyrolSport UG side mount(Known as the UG SMIC in the charts below), and a front mount. The aftermarket FMIC will not be named for many reasons. The TyrolSport UG SMIC mounts in the stock location, uses stock hoses, and requires minor trimming to fit. The UG SMIC uses a bar and plate Bell intercooler core. The Front Mount is a popular unit, and resides on many 1.8Ts. We will not reveal the manufacturer of the FMIC, as the purpose of this test was data acquisition; not marketing, sales, or slander.

Welding Aluminum Intercooler Cores and Other Aluminum Components ALL ABOUT INTERCOOLING THE ADVANTAGES OF INTERCOOLING Intercooling a supercharged or turbocharged engine has several advantages. The first and most frequently considered advantage is increased air density with consequential increase in horsepower. As will be shown in this booklet, horsepower can be increased by as much as 18 % or more. Some of the other bene- fits of intercooling are in- creasing the detonation thresh- old. With a good intercooler you can generally run three to four ad- ditional lbs of boost with the same octane gasoline and ignition timing without ex- periencing detona- tion. An inter- cooler slightly reduces the thermal load across the en- gine. When the inlet valve closes, the charge air inside the cylinder can be as much as 175° F to 200° F cooler than a non-intercooled engine, depending on the effectiveness of the intercooler.

Effect of Various Ignition Timings on Combustion Process and Performance of Gasoline Engine. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 65(2): 545–554. This article deals with the effect of the ignition timing on the output parameters of a spark-ignition engine. The main assessed parameters include the output parameters of the engine (engine power and torque), cylinder pressure variation, heat generation and burn rate. However, the article also discusses the effect of the ignition timing on the temperature of exhaust gases, the indicated mean effective pressure, the combustion duration, combustion stability, etc. All measurements were performed in an engine test room in the Department of Technology and Automobile Transport at Mendel University in Brno, on a four-cylinder AUDI engine with a maximum power of 110 kW, as indicated by the manufacturer. To control and change the ignition timing of the engine, a fully programmable Magneti Marelli control unit was used. The experimental measurements were performed on 8 different ignition timings, from 18 °CA to 32 °CA BTDC at wide throttle open and a constant engine speed (2500 rpm), with a stoichiometric mixture fraction. The measurement results showed that as the ignition timing increases, the engine power and torque also increase.

  • A-6252 Timer Kit
    A-6252 Timer Kit IGNITION TIMING THE “A” NU-REX PRECISION TIMING KIT CRANKSHAFT DEGREE INDICATOR AND TOOLS Installation Instructions In order to properly set the timing, it is necessary to accurately know when the spark occurs in relation to the piston/crankshaft position. “Timing” or “strobe” lights produce a flash of light each time a spark “trigger” occurs. If the flash illuminates a reference dot on the crank pulley and a stationary degree indicator, the timing is then accurately and reproducibly known. This is the basic timing method. Timing lights are obtainable at swap meets for 6-volt and plug power and through mail order and auto stores for 12-volt, plug, and 110V AC power. 1. Remove the timing pin, reverse it, and reinsert it in its hole. 2. Pressing lightly on the pin, slowly hand crank the engine until the pin falls into the dimple on the camshaft timing gear. 3. Lightly clamp the permanent type crank degree scale in place with the passenger side engine mounting bolt. Align the scales to be parallel and just adjacent to the crankshaft pulley. It should NOT rub on the pulley. Then tighten the bolt for permanent mounting A permanent white dot/line (or temporary chalk mark) is placed on the pulley opposite the 0º line of degree scale. It is recommended that the TDC #1 piston position be confirmed by removal of the #1 spark plug and observation of the piston to determine that the timing pin and piston positions agree Some gear dimples have been found not to be in agreement.

  • Spark Plug Reading As I See It
    SPARK PLUG READING AS I SEE IT. The information and pictures in this section have been used by me for 40 years with good results. There are other ways to read plugs that I’m sure will give very good results, but this is the way I have done it. Your results may very. Because of so many other influences like the type of premix oil or fuel quality can change the way the spark plug will color. Be careful. Too lean can destroy an engine in seconds. Always be too rich (over dark) when you start to change your jetting. This does not mean only the main jet. The needle and needle jet, if too lean, can do just as much damage. On a motorcross or dirt track you are mostly on or off the throttle (main jet). When you tune for a road race or street bike you are using a lot more middle throttle (needle and needle jet). Always use a new sparkplug when you want to check your jetting. If the sparkplug already has color on it you will not be able to see any jet changes. Don’t throw away any of those plugs with color on them as they are still good, just not for tuning. Make sure the ignition timing is correct for your engine as well as the spark plug heat range. I have a chart for most of the OSSA engines in the tech section. If the wrong heat range plug is used you will not be able to get a correct plug reading.

  • Effects of Valve Timing, Valve Lift and Exhaust Backpressure on Performance 2 and Gas Exchanging of a Two-Stroke GDI Engine with Overhead Valves
    1 Effects of valve timing, valve lift and exhaust backpressure on performance 2 and gas exchanging of a two-stroke GDI engine with overhead valves 3 Macklini Dalla Nora*, Thompson Diórdinis Metzka Lanzanova, Hua Zhao 4 Centre for advanced powertrain and fuels (CAPF) – Brunel University London 5 Kingston Lane, Uxbridge, Middlesex UB8 3PH – United Kingdom 6 Corresponding author (*): [email protected] Phone: +44 (0)74630 95392 7 8 Highlights: 9 • Two-stroke operation was achieved in a four-valve direct injection gasoline engine; 10 • Shorter valve opening durations improved torque at lower engine speeds; 11 • The longer the valve opening duration, the lower was the air trapping efficiency; 12 • Higher exhaust backpressure and lower valve lift reduced the compressor work; 13 14 Keywords: 15 • Supercharged two-stroke cycle engine 16 • Overhead poppet valves 17 • Variable valve actuation 18 • Gasoline direct injection 19 20 Abstract 21 The current demand for fuel efficient and lightweight powertrains, particularly for application 22 in downsized and hybrid electric vehicles, has renewed the interest in two-stroke engines. In this 23 framework, an overhead four-valve spark-ignition gasoline engine was modified to run in the two- 24 stroke cycle. The scavenging process took place during a long valve overlap period around bottom 25 dead centre at each crankshaft revolution. Boosted intake air was externally supplied at a constant 26 pressure and gasoline was directly injected into the cylinder after valve closure. Intake and 27 exhaust valve timings and lifts were independently varied through an electrohydraulic valve train, 28 so their effects on engine performance and gas exchanging were investigated at 800 rpm and 29 2000 rpm.
