    thus yielding a lower total horsepower output

    That's simply not true from a pragmatic view. Like all applications, you then pick a gearing/#gears/transmission combination which is complimentary to both the engine's output and the specific application.

    Diesel engines are commonly used for extremely high HP output and used in conditions where gas engines typically fall apart after half the total work load. And what you consider a negative (low RPM) is actually a positive.

    One of the big problems of high RPM is poor scavenging efficiency. That means as RPMs rise, overall efficiency decreases. Once you start reach 5500+ RPM, scavenging and lifter assembles becomes major bottlenecks to performance without a forced induction. That's why you rarely see production vehicles creating peak HP over 5000 RPM; even with forced induction. And far more typically for V8s, peak is usually somewhere between 3600-4500 RPM. Modern turbo diesels are typically maxing RPM at around 3000 RPM. And as they are designed differently, they typically provide optimal output all the way up to peak RPM because of their steep torque curves.

    Additionally, gas engines typically have what is dubbed a "power band". Most performance engines don't start making any significant HP until they reach a specific RPM, for a variety of reasons. For many V8s, this typically starts around 2100-2800 RPM; effectively providing meaningful HP output between 2100 - 4500 RPM. That's a "usable" power band of 2300 RPM. Contrasting that with diesel engines, which typically have a power band of 1500-2500 RPM. Suddenly the gas engine doesn't look so attractive.

    This distinction is very important to keep in mind as gas engines typically produce very little HP on the bottom end; while those that do typically produce very poorly on the top end. Furthermore, because they must build RPM to create HP and those engines which are designed for top end power, are typically very inefficient on the bottom end. That's why the first two thousand RPM is typically not outputting much HP and as its lacking torque compared to diesel, it takes longer to build.

    Long story short, far too many people drastically underestimate diesel potential while at the same time drastically over estimate gas' utility.

  3. Re:Frankly I Recommend Such Things on World's Only Diesel-Electric Honda Insight · · Score: 1

    That's the case for several reasons.

    Technically, diesel should be cheaper. The problem is, just as modern diesel engines started to grab traction in the US, lobbyists required ultra low sulfur diesel production. This caused the price to almost double over night. Likewise, gas production has continue to rise which places additional pressure to contribute more processing time to gas rather than diesel. While diesel/kerosene/jet fuel is really a byproduct of gas production, the new found processing requirements are not. Remember, 40%-60% of all gas production basically creates diesel/kerosene/jet fuel. If we shifted the sulfur requirements to a more reasonable level (modern diesel is already much, much cleaner than gas) and a bulk of US cars shifted to diesel, the cost of diesel would drastically drop. There is absolutely no reason diesel fuel should cost anywhere near that of gas unless its politically manipulated to force/justify its pricing higher. And don't forget, also requires yet additional additives to obtain its octane rating which the vast majority of the cars on the road no longer require.

    In short, if the oil companies were forced to remove the additives which they needlessly charge premium for, gas prices could drop 15-30% (local regulations and legal requirements drive this) over night. Remember, the vast majority of cars sold since the early 80's no longer require additional octane. Those that do can purchase additives and add it when they purchase gas. Likewise, diesel prices could drop almost 50%. And if the trend continued to shift the way of the diesel, diesel prices could drastically drop more.

    Diesels still don't put down a ton of horsepower

    Nothing could be father from the truth. HP is a function of torque. The reason you equate HP to high RPMs is because gas engines typically have poor torque curves compared to diesel so they have to make up for it with RPM. The base equation is hp=torque*rpm. That means you can produce HP by ramping up torque or by ramping up rpm. And since torque is what actually gets you moving, the performance advantage goes to diesel rather than gas. Likewise, its far easier to ramp up torque with diesel than it is rpms. Conversely, for gas engines, its far easier to ramp up rpm than torque because of fuel limitations (octane constraints). That's why you traditionally see high rpm gas engines and low rpm diesel engines.

    This is also why electric motors are used in trains - as they can produce high torque values at zero or near zero rpms. Oddly enough, they use diesel engines to run the generators which power those electric motors. The combination provides for incredibly high workloads which would otherwise kill gas engines. And even if you remove the electric motor, the advantage still goes to diesel.

    So don't let people blow smoke up your tail pipe. Diesel engines have a lot to offer. The days of low power, noisy, smoggy. and black smoke, rattle traps have long been gone from the diesel world.

    is it as gutless as I've been led to believe diesel cars are?

    Diesels haven't been gutless since the 80's. Diesels have come a long way, have better energy densities, better thermal efficiency, and generally far better torque curves than their gas cousins. And, modern diesels pollute far, far less than gas engines. Its a win-win. Its odd that about the same time diesels started grabbing traction in the US, diesel fuel regulations changed which forced diesel prices to almost double; thereby making it more expensive than gas despite the fact gas requires far more processing to produce while as the same time, diesel was typically considered the waste product of gas production.

    These days, diesels are used to compete in various rally races across the world because it means fewer stops for gas and they are ultra reliable. And guess what, diesels have consistently been winning races for many years now. Many motor sports are heading that way because they've proved to be superior. Simply put, its hard to explain the lack of diesel engines in American made vehicles other than by conspiracy. Of course that doesn't mean there is an actual conspiracy but diesels really are better in almost every way.

    Ignoring the long list of foolishness that is your statement about using FTP to transfer confidential and legally protected patient information, none of that really matters.

    In traffic shaping, you're typically not limiting bandwidth but rather latency. Applications which require low latency (games, ssh, video conferencing, VoIP, etc), can be granted priority ensuring their packets are placed in front of bulk transfer protocols. The bandwidth remains the same but the overall user experience is improved. Only in situations where bandwidth limits are reached for extended durations will shaping (good implementation) actually compromise bandwidth. And in the end, even in that situation, its more important interactive users observe a low latency experience than it is for your FTP transfer, taking for example sixty seconds, to complete three seconds faster.

    And really none of that matters. What they want is to broker deals with specific providers such that data routed to/from those providers receive a richer experience. So if you go to CNN, you can start watching them in five seconds. For video content coming from AOL, suddenly you'll have to wait tens of seconds to start watching. And if the game you want to play isn't hosted on a "sponsored provider", suddenly the game will be unplayable. That most certainly is not the Internet anyone wants, save only for greedy, POS ISPs.

    From my own experience, without fail, this is typical out sourcing results. Foreign outsourcing claims they can do x at price point y where y is substantially cheaper than local competition. Come the end of the project term, 1/2x is delivered at price y. Then round after round and takes place to push 1/2x up to original x requirements. Only to achieve that result, they spend 3y to finally deliver on x, which is now 1/2 year to 2 years late; or the project was flat out canceled. Even worse, to obtain the shoddy results, they wind up spending far more than it would have cost to simply to do it right the first time around. And, had they made the local investment, future upgrades, updates, and new projects would be cheaper because of a shorter delivery as they already had the expertise.

So start a project now and then start a new project based on the original two years from now, chances are you're staff will be as fresh then as it was when the original project started.
