Well here we are at the start of a new era in forklifts with the new regulations s on emissions now applying for forklifts over 58KW engines. from what i have heard all companies have gone with EGR how will this effect tier 4 final in 2015 ware SCR is going to be needed will be anybody's , from what i have herd many are having problems with EGR so SCR will be interesting because more room is needed for cooling and extra tank. Then again these only comply in North America and Europe so who is going to bother will many companies other small forklift under 5,000kg
