Exhaust and Airflow Basics Exhaust systems make power by getting used gases out of the engine which makes room for more air and fuel in the cylinder.
Exhaust gas analysis for motorcycle tuning. The exhaust gas analyzer. The Importance of Using Exhaust Gas Analyzers EGA for Superior Motorcycle Performance Tuning. HC Hydrocarbons concentration of the exhaust in parts per million ppm.
Inside a header with the engine running waves of exhaust passing through the tubing are more or less manipulated to extract the burned gases from the combustion chamber. At Bridge Analyzers we know motorcycle. Professional Combustion Analyzer by Forensics USA NIST Calibration HVAC Combustion Flue Exhaust Gas CO O2 COAF EA Filters and Probe Color Display Graphing Data.
Critter Retired twice. Note that being an emissions adjustment this in no way results in the optimum setting four your motorcycles carburetors. Motorcycle Repair Building and Restoration.
The HM5000 can also measure and record your vehicles engine speed along with all five gases. Jump to Latest Follow 1 - 4 of 4 Posts. At idle adjust the idle mixture screws until CO in the exhaust pipe is between 2-4.
The CO Series 2500 is our most user friendly and feature rich of our CO analyzer products. Get instant readings on up to five gases plus Air to. An incredibly powerful tool that despite its longevity on the automotive scene is under appreciated by many.
We need to know what the Gas Analyser measures. If CO cannot be set above 2 increase the slowpilot jets one size. 146-148 Is acceptable as long as Lambda is 1.
The engine test setup includes a. Some exhaust headers are tuned so the exhaust pulses enter the exhaust manifold between the exhaust pulses from other cylinders preventing interference between the exhaust pulses. It isnt a theoretical target like AFR of 1471.
The EGAs troubleshooting and tuning potential is huge. Navy and as a govt contractor. In the header a smaller tube diameter will increase the velocity at a given RPM which might enhance the pressure wave tuning the second component and can be beneficial with regard to inertia effects.
ANALYSIS OF EXHAUST GAS COMPOSITION OF INTERNAL COMBUSTION ENGINES USING LIQUEFIED PETROLEUM GAS Saulius Mockus Jonas Sapragonas Agnius Stonys Saugirdas Pukalskas1 Dept of Transport Engineering Kaunas University of Technology Kęstučio g. You not only get instantaneous readings of up to 5 gases youll also get Air to Fuel AFR Ratio Grams Per Mile GPM and Lambda which will help you in tuning that ever so tricky carburetor or injection system. Unburned Petrol represents the amount of unburned fuel due to incomplete combustion exiting through the exhaust.
Analysis of exhaust gas from combustion engines can help evaluate engine performance and diagnose problems. Joined Dec 9 2012 15179 Posts. In this experimental work exhaust gas analysis of an eight cylinder and v-type gasoline engine namely a Chevrolet 57 is experimentally performed in terms of engine speed at laboratory conditions by using of an exhaust gas analyzer and the special software called NetDyn and WinDyn.
This is a necessary evil. Tuning an exhaust system to a given application is a case-by-case basis challenge. Simultaneously those waves of exhaust help the intake side by pulling in a fresh air-fuel.
Exhaust Scavenging 101. 147 Parts air to 1 part fuel or gasoline. Lambda is a better measurement because it indicates true air to fuel balance.
Simply connect the HM5000 to your vehicles exhaust while you drive and in less than a second youll see the exhaust gas composition. If CO cannot be set below 4 decrease the slowpilot jets one size. Measuring carbon monoxide from 0 to 10 requires it to be turned on and a probe inserted into the motorcycles exhaust pipe.
General rules of thumb are easy to grasp but applying them correctly is where things get tricky. 27 LT-44025 Kaunas Lithuania. If the exhaust pressure pulses interfere with each other the exhaust flow is slowed causing a decrease in volumetric efficiency and thus decrease in horsepower.
This makes tuning motorcycles a slightly more delicate affair especially where changes in airflow into and out of the engine are concerned. The instantaneous velocity of the exhaust gas flow at any point is determined by the pressure gradient and the cross-sectional area at that point. What Does an Exhaust Gas Analyzer Measure.
It is designed to be fast and portable with its own battery pack. Check out Exhaust gas analysis here. But before you do you should make sure your bike is tuned up and ready to perform like the beast it is.
The displacement exhaust valve size induction system cam profile exhaust port design and RPM range all factor into deciding what form the exhaust system should take. Determine the exact amount of Hydrocarbons HC Carbon Monoxide COCarbon Dioxide CO2 Oxygen O2 and Oxides of Nitrogen NOx your vehicle is emitting. These are the gases that the 4 or 5-gas Gas analyser sees in a petrol engine.
