With Soaring Cost of Gas, It?s Time for Diesel Engines?

With soaring cost of gas, it’s time for diesel engines?

Hybrids might be the fad right now but have you considered the new diesel engines coming out of Europe? In the last few years, most European countries have adapted diesel because of the technological advances that made it more reliable and a good alternative for gas guzzling engines.

Diesel engines can deliver extra power compared to any gas engines invented including hybrids which relies on the combination of gas engine and electric motor. Diesel engines are simple to operate and are known to produce higher torque and fuel efficiency which 30%-40 % higher than gas engines. Hybrid might deliver more mileage but the developed pulling torque of diesel engine is unequal. This is attributed to high compression of diesel which is 3-4 times that of gasoline engines.

Tip:

In 2006, a German auto maker unveiled a 2 cylinder turbo diesel car that developed 20 hp with a fuel rating of 157 mpg. This is unheard of on any fuel rating produced by hybrid cars. The car also can seat 4 passengers.

In the first oil crisis of 1970s, a few diesel cars appeared in North America and it was a disaster. Those cars were noisy, very slow and emit lots of black smokes. The fuel injection was based on a single fuel pump driven by the front camshaft gear and hard to control. This resulted in over fueling which has 2 devastating effect: black smoke and detonation since the engine cannot burn all the fuel. Furthermore, because the fuel injector timing is not based on specific load and rpm, it resulted in poor acceleration.

A better fuel management must be found to resolve this problem.

With advances in gasoline electronic fuel injection management, it was also adopted for diesel engine. One of them is the use of electronic common rail fuel distribution system. Using a solenoid for each cylinder coming from the common rail, fuel can be better managed since the engine computer can control the solenoid. This made combustion complete and eliminated the excess fuel that was causing poor acceleration and gas emission. A new turbo charger technology was also added to get more exhaust air at lower rpm. With these 2 additions, the new diesel engines run quieter in various rpm loads.

Although diesel fuel has a higher energy per-liter content compared to the same liter of gasoline, it has 15% more greenhouse gas emissions. This can be blame on sulfur which is added to diesel fuel for lubrication purposes. Sulfur also cause the formation of particulate matter which is a miniature carbon like particles formed after combustion. When breathe into our lungs, this particulates are hazardous to our health. To remedy this, a double air filtering system is added to the engine so the particles can be collected and recycled back to the combustion chamber. This eliminates pollution and made the engine run more efficient. Finally, since diesel engines are also known to produce Nitrogen oxides which cause acid rain, an exhaust gas recirculation (egr) system was also added.

Overall, the performance of the new diesel powered cars is very encouraging. On a test conducted on VW TDI engine recently, it showed one of the best mileage ratings for engine performance. Compared to hybrid engines, diesel engine is not complicated and cheaper to operate. This was made possible because of the innovations in electronic fuel injections which made it reduced emissions to help our environment. If you want to save money on gas bills and have a strong reliable engine, diesel engines might be the answer we are looking for.

Fall Into Lower Electric Bills – the Fall Season is a Perfect Time to Lock in a Lower Electric Rate

Filed under: Changing energy supplier — Tags: , , , , , , , , , — admin @ 10:33 pm

As a full-time energy analyst and business owner (www.ChooseEnergy.com), people always ask me – when is it a good time to lock in an electric rate?  Well, you can “fall” into lower electric rates if you lock in during the fall months.  There are peeks and valleys (head and shoulder) months in regards to energy prices.  Electric rates track closely with natural gas prices and historically the months during the fall are valleys or shoulder months which makes for a good curve when trying to determine when to lock in your electric rate. 

So what should you do?  There still seems to be a premium on pricing out in 2012 and 2013 so I would recommend signing either a 12 or 24 month contract at the present time. This is where the rates are most attractive and the best time to end your contract during these same shoulder months so you can renegotiate during the low season.

Just as the Internet has made it easier for people to compare mortgages, travel rates and other services, ChooseEnergy.com has developed a compare and buy site that offers a trusted and objective comparison of available Texas electricity providers for residential and small commercial customers.  Not only do we select the providers that participate on our site, but we also show their most attractive rate plans for your home or business.  Plus, as I mentioned the fall season is a great time to lock in a lower Texas electricity rate.  Electricity prices usually track with natural gas costs, and natural gas is traditionally lower in shoulder months during the fall and spring season, before consumer demand increases during the cold winter months when consumers are using more natural gas. 

As I mentioned in a previous post – just like cell phone providers – like AT&T or Sprint – Retail electric providers bid on customers’ electricity business.  These providers can also personalize their bids to each customer or modify their offers and terms as often as they wish.   For instance, electricity retailers may offer exceptionally competitive rates tied to longer term contracts (but we recommend not signing longer than 36 months at the present time) to attract customers in a targeted geographic area or offer a renewable energy product, like energy produced from wind, for the same price as you are currently paying.  

It certainly pays to not only get the right offering that fits your home or business needs, but also getting that offering at the right time.  So do some shopping for your home or business during this holiday season and take advantage of fall electric rates.

Jerry Dyess is the President & CEO of ChooseEnergy.com (www.ChooseEnergy.com) – Choose Energy is a neutral service that compares offers from the best Texas energy providers to help residential and small business customers choose the best energy plan for their home or business. Residential and business customers now have a simple way to compare offers made by different Texas electricity companies and switch to their choice of preferred provider in just a few clicks. Choose Energy gives consumers the power to save money on electricity while making educated choices based on accurate, up-to-date, comparable information.
