  • The Turbo Shop | What is engine knock/ detonation.
    vastly different when it comes to knock resistance there is no single answer to how much Design features such as combustion chamber geometry spark plug location bore size and compression ratio all affect the knock characteristics of an engine 2 Ambient air conditions For the turbocharger application both ambient air conditions and engine inlet conditions affect maximum boost Hot air and high cylinder pressure increases the tendency of an engine to knock When an engine is boosted the intake air temperature increases thus increasing the tendency to knock Charge air cooling e g an intercooler addresses this concern by cooling the compressed air produced by the turbocharger 3 Octane rating of the fuel being used octane is a measure of a fuel s ability to resist knock The octane rating for pump gas ranges from 85 to 94 while racing fuel would be well above 100 The higher the octane rating of the fuel the more resistant to knock Since knock can be damaging to an engine it is important to use fuel of sufficient octane for the application Generally speaking the more boost run the higher the octane requirement This cannot be overstated engine calibration of fuel and spark plays an enormous role in dictating knock behavior of an engine This entry was posted in engine technology and tagged detonation TURBOCHARGER Bookmark the permalink Post navigation Air Fuel Ratio tuning Rich v Lean Cimat Balancing Machines CONTACT US Unit 16 6 Pyott street Korsten Port Elizabeth South Africa Tel 041 4510025 Mobile 072 1877214 Int 27 41 4510025 Fax 086 6057963 nick theturboshop co za Please note Google maps shows Pyott street as Pogson street Techno News and Articles 2 stage turbo systems We have moved VNT what it does oil related failure Cimat Balancing Machines What is engine

  • The Turbo Shop | Air/Fuel Ratio tuning: Rich v. Lean
    14 7 1 stoichiometric AFR therefore it is a richer mixture Conversely a higher AFR number contains more air and therefore it is a leaner mixture For Example 15 0 1 Lean 14 7 1 Stoichiometric 13 0 1 Rich Leaner AFR results in higher temperatures as the mixture is combusted Generally normally aspirated sparkignition SI gasoline engines produce maximum power just slightly rich of stoichiometric However in practice it is kept between 12 1 and 13 1 in order to keep exhaust gas temperatures in check and to account for variances in fuel quality This is a realistic full load AFR on a normally aspirated engine but can be dangerously lean with a highly boosted engine Let s take a closer look As the air fuel mixture is ignited by the spark plug a flame front propagates from the spark plug The now burning mixture raises the cylinder pressure and temperature peaking at some point in the combustion process The turbocharger increases the density of the air resulting in a denser mixture The denser mixture raises the peak cylinder pressure therefore increasing the probability of knock As the AFR is leaned out the temperature of the burning gases increases which also increases the probability of knock This is why it is imperative to run richer AFR on a boosted engine at full load Doing so will reduce the likelihood of knock and will also keep temperatures under control There are actually three ways to reduce the probability of knock at full load on a turbocharged engine reduce boost adjust the AFR to richer mixture and retard ignition timing These three parameters need to be optimized together to yield the highest reliable power This entry was posted in Uncategorized Bookmark the permalink Post navigation Choosing the right turbo part3 What

  • The Turbo Shop | technology info regarding compression ratios
    that affect the maximum allowable compression ratio There is no single correct answer for every application Generally compression ratio should be set as high as feasible without encountering detonation at the maximum load condition Compression ratio that is too low will result in an engine that is a bit sluggish in off boost operation However if it is too high this can lead to serious knock related engine problems Factors that influence the compression ratio include fuel anti knock properties octane rating boost pressure intake air temperature combustion chamber design ignition timing valve events and exhaust backpressure Many modern normally aspirated engines have well designed combustion chambers that with appropriate tuning will allow modest boost levels with no change to compression ratio For higher power targets with more boost compression ratio should be adjusted to compensate There are a handful of ways to reduce compression ratio some better than others Least desirable is adding a spacer between the block and the head These spacers reduce the amount a quench designed into an engine s combustion chambers and can alter cam timing as well Spacers are however relatively simple and inexpensive A better option if more expensive and time consuming to install is to use lower compression pistons These will have no adverse effects on cam timing or the head s ability to seal and allow proper quench regions in the combustion chambers This entry was posted in Uncategorized and tagged compression ratio technology turbochargers Bookmark the permalink Post navigation INDY OIL Choosing the right turbo part1 CONTACT US Unit 16 6 Pyott street Korsten Port Elizabeth South Africa Tel 041 4510025 Mobile 072 1877214 Int 27 41 4510025 Fax 086 6057963 nick theturboshop co za Please note Google maps shows Pyott street as Pogson street Techno News and Articles 2
