Just because a motor vehicle power source has low emissions, does not necessarily mean that it will be highly efficient.
Emissions controls refer more to the evaporative and exhaust filtration systems than the native ability of an engine to best vaporize and spark its mixture to the highest level of efficient burn and creation of transmissible power.
Some engines and some transmissions for that matter create more heat when what they should be creating is more power. Additionally, many motors send unburnt fuel into the catalytic converter for the purpose of finishing the job the engine was supposed to do in the first place. Heat is as per Carnot a byproduct of power, but also a product of inefficiency. Higher octane fuels have higher potential energies than lower octane fuels.
The higher the octane, the longer the burn. The longer the burn, the more power is generated during the combustion stroke. Therefore, fuel economy is increased. The math can often be such that 91 octane fuel costs less to use despite its higher initial cost at the pump.
A caveat here: Higher octane fuels can only release their increased potential energies in engines that have higher compression ratios, and that run at hotter temperatures. Compression ratios of 9. This is why there has been such a trend over the past several years to run engines hotter, typically into the F. Another benefit of this hotter operating temperature is both in increased burn and cleaner exhaust emissions.
Well, there is no love lost here for either of the above, but more sinister and problematic than corruption and profiteering is the stone-cold fact that the cost of petroleum is actually quite stable compared with precious metals, commodities and a weighted basket of world currencies.
The lb. The right transmissions will have a broad gearing span for both efficient cruising RPM's and a good gearing for off-road use. Don't forget that the torque converter of an automatic is much like a gear reduction unit - the automatic of your choice will not list a compound low gear, but lower gearing is effectively achieved by the differential of the power transmitting fluid. In terms of automatics, you may consider a THC, which features a lockup torque converter. These feature an overdrive gear and a lower first gear than just about any automatic shift transmission available.
Additionally, their design and construction is world class tough and refined. As discussed above, this will put your engine in its optimally efficient range while cruising. There is no better place to do this than on the Novak Gearing page, here.
A V8 that has the crawling torque of a straight-six-cylinder and the efficiency of a V6 cruiser is better than a torque oriented I6 or V8. While these engines do have an initially good torque boost, they do not have the legs required to get out and run without creating too much heat and wasted fuel.
Remember here that power is economy. A quality V6 and V8 can be a very efficient and broadly usable platform. Nearly all straight-sixes and oversize V8's cannot inherently achieve the economies of power. Next, we highly encourage you to consider a throttle body or multi port injection engine.
We remain hopeful that the other up and coming modern engines can do as well. We get an occasional call from customers that have found a beautiful Vortec V8 and ask if they can put a "simpler" carburetor on it.
This has every distinct disadvantage that we can think of: increased parts cost, decreased efficiency, driveability and reliability. Don't even think about it. Fuel injection especially GM fuel injection is much easier to work with than too many people think.
Some four-wheel-drives simply have wasteful designs in their systems. There is a cost to running all-wheel-drive transfer cases and axles.
The trial was also controversial because immediately prior to the election, criticism was levelled at the encryption scheme used to protect votes being sent across the net. Software experts called for the entire voting system to be rewritten to better protect data. A report looking into the success of the trial said about 70, Norwegians took the chance to cast an e-vote. However, it said, there was no evidence that the trial led to a rise in the overall number of people voting nor that it mobilised new groups, such as young people, to vote.
The report by Norway's Institute of Social Research also expressed worries about the fact that online voting took place in what it called "uncontrolled environments". This, it said, undermined the need for a vote to be made in secret without anyone influencing the voter as they made their choice.
