香港の過酷な運行環境にも対応する高性能なエンジン


貿易と金融の中心地であり、観光地としても人気を集める街、香港。2階建てバス(ダブルデッカーバス)が走る賑やかな街をイメージされる方も多いでしょう。そのイメージ通り、街の中には路線が網の目のように張り巡らされ、毎日400万人以上もの人々(2019年時点)がバスを利用しています。


私たちは長年、香港の交通網を支えるバスにエンジンを提供してきました。2020年にはL9エンジンを載せた「ADL Enviro500」が新たに導入され、香港を走る3軸2階建てバスの約7割にあたる4500台がカミンズ製エンジンとなりました。


香港では、湿度の高い気候の中、乗客を満載して急勾配の道を走ることが求められます。そのため、パワーと安定性はバスエンジン選びの重要な要素となります。L9エンジンはクラス最高の出力性能を備えており、非常にパワフルなのが特徴。可変容量ターボチャージャー(VGT)を備えているため加速性にも優れ、静かでスムーズな運行が可能です。さらに、街中や郊外で使用された場合は1日20時間の稼働に、高速バスとして使用された場合は年間20万kmもの走行に耐えられることが証明されています。


また、香港で運行するバスは、EUによる大型トラックやバス向けの排ガス規制「Euro VI」の基準を満たす必要があります。これに対応するため、カミンズはL9エンジンに「選択触媒還元脱硝装置(SCR)」および「ディーゼル微粒子捕集フィルター(DPF)」を統合した排出ガス後処理システムを搭載。排出ガスの削減にも成功し、香港の厳しい運行環境に対応するエンジンを実現させました。

5 businesses that can benefit from selling Cummins generators

Cummins dealer discussing home generator

Ninety percent of American business are small- and medium-size. They are the true engines of our economy, employing millions of workers. With many of them looking for new ways to expand their services, generate income and grow their businesses, Cummins home standby and portable generators could be a new source of revenue. 

A Silver Lining in Dark Clouds

According to the Associated Press, power outages from severe weather have doubled over the past two decades, straining our country’s aging power grid. This has increased the frequency and duration of power outages. These frequent outages create a need for reliable backup power for households and other businesses. And for enterprising small- and medium-size businesses, satisfying this need with Cummins generators is a huge opportunity.   

Which businesses could benefit the most from becoming Cummins authorized dealers? Here are our top five:

1. General Contractors — When natural disasters such as ice storms, hurricanes, high winds, forest fires or earthquakes hit, lost power isn’t the only challenge customers face. There is often physical damage to property that must be repaired. When they are helping customers to rebuild, general contractors have an opportunity to estimate home or business’s energy needs and suggest adding a Cummins QuietConnect™ Home Standby Generator. If the customer agrees, the general contractor not only profits from the sale of the generator, but also the labor to install it.

2. Electricians — A good electrician is a trusted source of information. Not only are they experts with the flow of electrons, they often know their customer’s specific electrical setups. After a prolonged power outage, many are often asked “Is there anything you can do to keep my electricity on the next time the power goes out?” Electricians who sell and install Cummins QuietConnect Home Standby Generators can say, “Yes, yes there is.” Installing home standby generators can be another valuable service that electricians provide.

3. Heating & Cooling Contractors — During a power outage, one of the most critical systems knocked offline for home and business owners is their central heating and cooling system. Going without heat or cool air for a long period of time is not only uncomfortable, it can be dangerous if the temperatures are extreme outside. So, naturally, once power is restored, finding a way to keep the HVAC system on during the next power outage becomes top-of-mind. Since heating and cooling contractors are experts at installing large systems in homes and businesses, adding Cummins QuietConnect standby generators to homes and businesses is a natural way to add another profit center to their businesses.

4. Online Retailers — Up until now, we’ve been discussing standby generators. For businesses that don’t specialize in installing generators permanently into place, Cummins portable generators can be a moneymaker.  While portable generators can be used during power outages, they are better suited to smaller tasks due to their portability. This makes them ideal for camping, tailgating, construction worksites and more. With Cummins’ rugged and reliable reputation, our portable generators are ideal for retailers focused on these market segments.

5. Solar Panel Installers — Most home solar panels are connected directly to the power grid. So, when the power goes out, the solar panels stop providing power. For a backup source of electricity, solar panel installers can either install a solar battery backup, which gets charged by the solar panels, or a home standby generator. Typically, solar battery backups can only power a home for a few hours, so if an area is prone to weather-related outages, a home standby generator such as the Cummins QuietConnect is the better choice.

Heat waves that cause excessive demand for electricity…droughts that make hydropower less available…power grids near active wildfires shut down for safety…aging, overstressed power grids…high winds that snap powerlines…these are all reasons why some parts of the country may face planned power outages this year.  

If you live in an area prone to rolling blackouts, here are some tips to help you ready your family for them: 

  • Sign up for notifications from your local electricity utility — If this service is available from your local utility, it can give you a warning to start preparing before the power goes out. 
  • Download our Power Outage Ultimate Checklist — It provides in-depth information about what to do before, during and after an outage. It even shows you what to do for children, pets and family members with medical needs. You can download it here
  • Stockpile nonperishable food and water — Make sure you have a manual can opener, too. Plan to have enough for everyone so your family can stay hydrated and nourished during the blackout. 
  • Make or purchase ice and coolers — If you have enough warning, make or purchase ice so you can pack some of your perishable food in coolers to preserve it. (A refrigerator will only maintain its internal temperature for about four hours, a freezer for about 48 hours.) 
  • Buy flashlights and extra batteries — Blackouts can be, well, black. Flashlights can be used for safety if you need to move around at night but use them sparingly. Make sure you have enough for every family member.
  • Keep mobile phones charged and gas tanks full — Your phones and your vehicles are your lifelines to the outside world. If you have an EV, make sure it’s fully charged. 
  • Practice manually opening garage doors — If you need to drive somewhere, you first need to be able to get your car out of the garage. 
  • Plan for medications that require refrigeration — You may need to store them in a cooler like your refrigerated food until the power returns. 
  • Invest in a whole-home standby generator — For the ultimate peace of mind, consider one of the Cummins QuietConnect™ home standby generators. In the event of a power outage, your generator will automatically switch on and keep your home powered.  
  • Install carbon monoxide detectors with battery backups — Place them in central locations on every floor so if any carbon monoxide gets in the home, you are immediately alerted. 

Rolling blackouts seem to be becoming more and more common. Fortunately, there are ways to plan ahead and keep them from completely disrupting your life.

Rebuild masterstroke pays off for miners

A masterstroke by Cummins engineers in Australia and the US has resulted in major cost reduction and environmental benefits for mining companies electing to rebuild their QSK60 engines under a special upgrade program.

The engineers focused on rebuild possibilities for the early generation QSK60, and how it could be upgraded to the latest diesel technology at overhaul time with no major change to the base 60-litre V16 design – a feat that eluded other engine manufacturers.

The key technology upgrade is to fuel injection, with the early unit injection system (HPI) replaced with the high-pressure modular common rail system (MCRS) that is now featured on all of Cummins’ latest generation high horsepower engines.

The 300th upgraded engine, rated at 2700 hp, recently rolled off the production line at the Cummins Master Rebuild Centre in Brisbane, highlighting yet another successful step in the evolution of the QSK60 and why it is the foremost high-horsepower diesel engine globally in mobile mining equipment.

“Reduced fuel consumption and longer life-to-overhaul are keys to lower total cost of ownership, and they were the initial aims behind the engineering of the upgrade program for the QSK60,” says Greg Field, mining business development manager for Cummins Asia Pacific.

“Innovation is at the core of Cummins’ long history, and it has certainly played its part in the QSK60 rebuild options we can offer our mining customers.”

The bottom line is impressive: Diesel particulate emissions are slashed by up to 63% through in-cylinder combustion technology with no aftertreatment. There’s also a plus for maintenance with less soot loading in the oil.

Fuel savings up to 5% are consistently reported in the field for significant greenhouse gas emissions reduction, while life-to-overhaul is extended by 10%, translating to fuel consumption of more than 4.0 million liters before rebuild is required.

Apart from the fuel system upgrade to MCRS, the QSK60 with single-stage turbocharging also features other Cummins innovations in combustion technology that were engineered for Tier 4 Final and Stage V emissions compliance, the most stringent off-highway emission standards in the world.

The rebuild upgrade package can be applied to the two variants of the QSK60 – one with single-stage turbocharging (known as ‘Advantage’) which can be rated from 1785 to 2700 hp, the other with two-stage turbocharging which can be rated at 2700, 2850 or 3000 hp.

The 300th upgraded QSK60 went to Boggabri Coal in the NSW Gunnedah Basin for installation in a Komatsu 930E haul truck. The engine has proved its worth in both coal and iron ore mining in Australia.
