Innovation You Can Depend On Summary Cummins is on plan to deliver fuel economy 40% improvedover that of the baseline gasoline power train while alsomeeting the requirements of Tier2Bin2 tail pipe emissions. Technical focus over the past year has been centered on newengine installation and performance assessments The new engine has achieved target engine out emissions,performance and fuel economy. Demonstrated catalyst performance has met or exceededtargeted conversion rates.– Increased allowance on engine out HC Cummins and our partners are developing technology toimprove the overall engine package;– JM – Delivering materials for low temperature emission mitigation– Nissan – Guiding hardware updates to vehicle systems for up to datetechnology improvements and feedback on overall vehicle NVH andperformance feel.19This presentation does not contain any confidential, proprietary, or otherwise restricted information.

Technical Approach – High EfficiencyEngine weight control via design featuresInnovation You Can Depend On Goal: equivalent application weight as baseline engine Light weight steel piston for reduced friction &compression height with increased power density Reduce deck height reduced cylinder block weight Aluminum cylinder head and block Reduced weight and physical size Create a weight allowance for emission control devices Low thermal mass exhaust manifold for rapid warm up Reduced mass & thermal load vs standard cast iron construction Forged crankshaft with smaller (than cast) journals andincreased strength for power density Smaller and lighter vs standard cast iron21This presentation does not contain any confidential, proprietary, or otherwise restricted information.

Innovation You Can Depend On Technical Approach - Exhaust SystemConfiguration22 Close coupled filter system to enable low pressure EGR SCR coated on filter (SCR-F) allows for close coupling of SCR function forfast light off Use of a direct ammonia delivery system (DADS) can further improve NOxconversion performance by reducing the time delay before NH3 introductionafter cold start DADS also allows for multiple NH3 dosing locations, which allows for theintegration of additional under-floor SCR elements to mitigate IRAFThis presentation does not contain any confidential, proprietary, or otherwise restricted information.

a. If conversion of one mole of ATP to ADP P i releases about 7.3 kcal, roughly speaking, how many moles of ATP need to be produced per day in order for this energy need to be met? 3000 kcal/day divided by 7.3 kcal/mole of ATP 411 moles of ATP b. If the molecular weight of ATP is 573, how much would the required ATP weigh in kilograms?
