adhikansh upkaran input dabaav key roop mein kewal isaliye upayog karate hain kyonki sadharan 100psi gaze kaa upayog kiya jaa sakata haye joe 100% seey mell khaata haye lekin usase aage usa dabaav kii koee aavashyakta naheen haye. oopar diyaa gayaa koee bhee dabaav maap key uddeshyon key liye thheek-thheek kaam karega, halanki risaav kii aavaaz utani tej naheen hogi. risaav key shore key alawa, risaav kaa ingit pratishat kabhi-kabhi niyaamak dabaav aur chhidra key aakar key saath bhinn hoga. 100 pee. aiss. aaee. aur 030 "chhidra key saath, ack diyaa gayaa cylinder 20 pratishat risaav dikhaa sakata haye. 50 pee. aiss. aaee. parr, ack hii cylinder mein 30 pratishat risaav yaa usee chhidra key saath 15 pratishat risaav dikhaai dey sakata haye. aisaa isaliye hotaa haye kyonki risaav kaa pravaah lagbhag hamesha bahut ashant hotaa haye. ashanti aur anya karakon key kaaran, jaise baithane kaa dabaav, pareekshan dabaav mein parivartan lagbhag hamesha cylinder risaav path dwara banaae gaye prabhaavi chhidra koo badal detaa haye.
metering chhidra key aakar kaa risaav pratishat parr seedha prabhaav padata haye. 
aam taur parr, ack vishisht motor vaahan injan parr 30-40 psi seey adhik dabaav daala jaataa haye, tou usey bund kiya jaanaa chaahiye yaa yeh pareekshan dabaav mein ghoom jaayega. ghoornan seey pahale sahan kiya jaane vaalaa sateek pareekshan dabaav rodd konn, boor, anya cylinders key sampeedan aur gharshan koo jodane parr atyadhik nirbhar kartaa haye. jaba piston sheersh mrit kendra mein hotaa haye, vishesh roop seey chhote boor injanon key saath, tou ghumaane kii pravritti cumm hoti haye. ghumaane kii adhikatam pravritti lagbhag aadhe stroke parr hoti haye, jaba chhad crankshaft key fenkane key samkon parr hoti haye.
saral nirmaan key kaaran, kaee yantriki apane swayam key parikshakon kaa nirmaan karate hain. ghar mein baney upkaran vaanijyik parikshakon key saath-saath kaam curr sakate hain, basharte kii way uchit chhidra aakar, achche dabaav maap aur achche niyamakon koo niyojit karein.
