MEASUREMENT PRINCIPLE Pre-filters remove particulates from the exhaust gas and prevent contamination of sample lines and emission measuring systems. Heated sampling systems allow switching an AMA i60 or a SESAM i60 FT to different sample points or lines. Sample points are often single cylinders of an engine, while sample lines are for example different testbeds that share one emission measuring system. Sample Selection Modules come with two to four inlets or up to 10 inlets and one out let. Additionally dual stream modules with up to nine inlets can be chosen. Depending on the specific model, further extensions are available, like additional inlet filters and flame traps, calibration gas inlets, backflush functionality, turbo pressure regulators, pressure drop and flow sensors. The Heated Boost Pump is required to overcome the pressure drop when there are very long heated sample lines. APPLICATION Depending on the engine and fuel type as wel l as the sample point (e.g. pre-cat, post-cat, post- DPF), different filter materials such as ceramic, fiber glass, stainless steel or t itanium can be used. Boost pumps are used in applications with very long distances (over 17 m) from the sampling point to the emission measuring system. Typical applications are test cell-sharing and large test cells as used in marine vessel engine test ing. Furthermore, boost pumps are applied in altitude and altitude simulation testbeds. BENEFITS AT A GLANCE • Extendable with e.g. pressure drop sensor, pressure regulation, etc. • Minimized delay time for transient measurements due to innovative valve manifold layout • Optimized design to mini- mize wall effects (hang-up) • Sample point and sample line switching (up to 10 inlets) • Boost pump with controlled recirculation circuit – no bypass required • Stand-Alone pre-filter to be connected to third- party equipment
